व भ न डिजटल ए सल काउटर क काड का तलना मक अ ययन Comparative Study of Cards of different Digital Axle Counters
Introduction Axle Counters play a very important role in detecting the presence of train vehicle thereby
ensuring safety in train operation Analog Axle counters on the Indian Railways were introduced
during the 1970s Digital Axle Counters were introduced in early 2000 Digital Axle counters
both Single Section and Multi-Section are installed on Indian Railways due to their wide
applications such as in Station yard Block working IBS Automatic Signalling and Point Zones
Over the years due to technological advancements a number of firms have come up with their
axle counters Following table shows the names of RDSO approved manufacturers and suppliers
of Digital Axle Counters on Indian railways along with the brief description of their model
Although the principle of working is same for all versions of Digital Axle counters their Card
configuration LED indications and parameters are different for different make There may be
more than one type of Digital Axle Counters installed in the section of an SSEJE or Signal
Maintainer hence often he has to refer data of different types of DACs
In view of above an effort has been made to compile the card related information of different
types of Digital Axle Counters mentioned as above in one single document for quick reference
by maintenance personnel This handbook covers brief description of cards their functions and
indications for diagnostics maintenance and important parameters An annexure has also been
added at the end of the handbook which contains relevant data for comparative study

3 Event Logger Card (Card 5)
For storage of events in the system
Event Logger card is designed to capture and store important signals from the remote and local SSDAC units The stored data can be downloaded from the event logger card for the purpose of analyzing the events occurring during the operations of the SSDAC The data can be analyzed with the help of CEL Data analyzer software
4 Modem Card (Card 6)
a Serial IO Multiplexer
V21 Modem is used for communication between two units of SSDAC The digital packets generated by MLB cards are sent to remote unit on a pair of cable Serial IO Multiplexer is used to select the micro controller card that will communicate with the modem on the remote unit
b Resetting Circuit
The SSDAC reset circuit is included in the modem card wherein the reset voltage window (42V to 52V) and reset timing window (between 02 and 10 secs) functions has been provided The reset command will not respond for the cases outside these windows

Comparative Study of Cards of different Digital Axle Counters March 2017
व भ न डिजटल ए सल काउटर क काड का तलना मक अ ययन Comparative Study of Cards of different Digital Axle Counters
Introduction Axle Counters play a very important role in detecting the presence of train vehicle thereby
ensuring safety in train operation Analog Axle counters on the Indian Railways were introduced
during the 1970s Digital Axle Counters were introduced in early 2000 Digital Axle counters
both Single Section and Multi-Section are installed on Indian Railways due to their wide
applications such as in Station yard Block working IBS Automatic Signalling and Point Zones
Over the years due to technological advancements a number of firms have come up with their
axle counters Following table shows the names of RDSO approved manufacturers and suppliers
of Digital Axle Counters on Indian railways along with the brief description of their model
Although the principle of working is same for all versions of Digital Axle counters their Card
configuration LED indications and parameters are different for different make There may be
more than one type of Digital Axle Counters installed in the section of an SSEJE or Signal
Maintainer hence often he has to refer data of different types of DACs
In view of above an effort has been made to compile the card related information of different
types of Digital Axle Counters mentioned as above in one single document for quick reference
by maintenance personnel This handbook covers brief description of cards their functions and
indications for diagnostics maintenance and important parameters An annexure has also been
added at the end of the handbook which contains relevant data for comparative study

86 व भ न काड क काय Functions of different Cards
(i) CPU Card (CPU1 amp CPU2) Failsafe 2 out of 2 architecture for controlling and monitoring the SSDAC for
reliable operation Houses the system software that schedules the overall operation as per
configuration
(ii) Phase Detector Card (PD1 amp PD2) A vital card that detects the movement of train axleswheels that is more than
550mm diameter Rejects trolley dolly spoke wheels and push trolley wheels Counts the total number of train axles and updates the system
50 CAMTECHSPROJ16-17HB-CCDAC10
Section VIII G36 GGTronics SSDAC March 2017
(iii) Communication Card (Com1 amp Com2)
Communication between two SSDAC systems is through FSK communication at 1200bps V23 standard along with CRC check
Vital data like axle counts and system status are transmittedreceived between the SSDAC system units
(iv) Relay Drive Card (RD1 ampRD2) Axles sensed by Detector Coils are fed to PD card which in turn feeds signal to
CPU The relay drive card receives instructions from CPU for actuating Vital relay for blocking a section as soon as the first axle is detected It is cleared after both IN and OUT counts of the section match
(v) Power Supply Card Generates required multiple power outputs from 24VDC input
(vi) SM-CPU or Event Logger Card Monitors the SSDAC system and logs vital events during normal and error
operation with date and time stamp As many as 95 different events are recorded Optional display connected to Event Logger Card displays the communication
errors happening in Real-time which aids in assessing the health of communication channel Event logged during normal operation Communication status ok Vital and Preparatory Relay pickup drop Reset operations
Event logged during error operation Communication link fail System down due to failure of any card Vital and Preparatory Relay error status +5 VDC variations Errors

Comparative Study of Cards of different Digital Axle Counters March 2017
व भ न डिजटल ए सल काउटर क काड का तलना मक अ ययन Comparative Study of Cards of different Digital Axle Counters
Introduction Axle Counters play a very important role in detecting the presence of train vehicle thereby
ensuring safety in train operation Analog Axle counters on the Indian Railways were introduced
during the 1970s Digital Axle Counters were introduced in early 2000 Digital Axle counters
both Single Section and Multi-Section are installed on Indian Railways due to their wide
applications such as in Station yard Block working IBS Automatic Signalling and Point Zones
Over the years due to technological advancements a number of firms have come up with their
axle counters Following table shows the names of RDSO approved manufacturers and suppliers
of Digital Axle Counters on Indian railways along with the brief description of their model
Although the principle of working is same for all versions of Digital Axle counters their Card
configuration LED indications and parameters are different for different make There may be
more than one type of Digital Axle Counters installed in the section of an SSEJE or Signal
Maintainer hence often he has to refer data of different types of DACs
In view of above an effort has been made to compile the card related information of different
types of Digital Axle Counters mentioned as above in one single document for quick reference
by maintenance personnel This handbook covers brief description of cards their functions and
indications for diagnostics maintenance and important parameters An annexure has also been
added at the end of the handbook which contains relevant data for comparative study

Comparative Study of Cards of different Digital Axle Counters March 2017
व भ न डिजटल ए सल काउटर क काड का तलना मक अ ययन Comparative Study of Cards of different Digital Axle Counters
Introduction Axle Counters play a very important role in detecting the presence of train vehicle thereby
ensuring safety in train operation Analog Axle counters on the Indian Railways were introduced
during the 1970s Digital Axle Counters were introduced in early 2000 Digital Axle counters
both Single Section and Multi-Section are installed on Indian Railways due to their wide
applications such as in Station yard Block working IBS Automatic Signalling and Point Zones
Over the years due to technological advancements a number of firms have come up with their
axle counters Following table shows the names of RDSO approved manufacturers and suppliers
of Digital Axle Counters on Indian railways along with the brief description of their model
Although the principle of working is same for all versions of Digital Axle counters their Card
configuration LED indications and parameters are different for different make There may be
more than one type of Digital Axle Counters installed in the section of an SSEJE or Signal
Maintainer hence often he has to refer data of different types of DACs
In view of above an effort has been made to compile the card related information of different
types of Digital Axle Counters mentioned as above in one single document for quick reference
by maintenance personnel This handbook covers brief description of cards their functions and
indications for diagnostics maintenance and important parameters An annexure has also been
added at the end of the handbook which contains relevant data for comparative study

Comparative Study of Cards of different Digital Axle Counters March 2017
व भ न डिजटल ए सल काउटर क काड का तलना मक अ ययन Comparative Study of Cards of different Digital Axle Counters
Introduction Axle Counters play a very important role in detecting the presence of train vehicle thereby
ensuring safety in train operation Analog Axle counters on the Indian Railways were introduced
during the 1970s Digital Axle Counters were introduced in early 2000 Digital Axle counters
both Single Section and Multi-Section are installed on Indian Railways due to their wide
applications such as in Station yard Block working IBS Automatic Signalling and Point Zones
Over the years due to technological advancements a number of firms have come up with their
axle counters Following table shows the names of RDSO approved manufacturers and suppliers
of Digital Axle Counters on Indian railways along with the brief description of their model
Although the principle of working is same for all versions of Digital Axle counters their Card
configuration LED indications and parameters are different for different make There may be
more than one type of Digital Axle Counters installed in the section of an SSEJE or Signal
Maintainer hence often he has to refer data of different types of DACs
In view of above an effort has been made to compile the card related information of different
types of Digital Axle Counters mentioned as above in one single document for quick reference
by maintenance personnel This handbook covers brief description of cards their functions and
indications for diagnostics maintenance and important parameters An annexure has also been
added at the end of the handbook which contains relevant data for comparative study

(i) CPU Card (CPU1 amp CPU2) Failsafe 2 out of 2 architecture for controlling and monitoring the SSDAC for
reliable operation Houses the system software that schedules the overall operation as per
configuration
(ii) Phase Detector Card (PD1 amp PD2) A vital card that detects the movement of train axleswheels that is more than
550mm diameter Rejects trolley dolly spoke wheels and push trolley wheels Counts the total number of train axles and updates the system

Section VIII G36 GGTronics SSDAC March 2017
(iii) Communication Card (Com1 amp Com2)
Communication between two SSDAC systems is through FSK communication at 1200bps V23 standard along with CRC check
Vital data like axle counts and system status are transmittedreceived between the SSDAC system units
(iv) Relay Drive Card (RD1 ampRD2) Axles sensed by Detector Coils are fed to PD card which in turn feeds signal to
CPU The relay drive card receives instructions from CPU for actuating Vital relay for blocking a section as soon as the first axle is detected It is cleared after both IN and OUT counts of the section match
(v) Power Supply Card Generates required multiple power outputs from 24VDC input
(vi) SM-CPU or Event Logger Card Monitors the SSDAC system and logs vital events during normal and error
operation with date and time stamp As many as 95 different events are recorded Optional display connected to Event Logger Card displays the communication
errors happening in Real-time which aids in assessing the health of communication channel Event logged during normal operation Communication status ok Vital and Preparatory Relay pickup drop Reset operations
Event logged during error operation Communication link fail System down due to failure of any card Vital and Preparatory Relay error status +5 VDC variations Errors

Comparative Study of Cards of different Digital Axle Counters March 2017
व भ न डिजटल ए सल काउटर क काड का तलना मक अ ययन Comparative Study of Cards of different Digital Axle Counters
Introduction Axle Counters play a very important role in detecting the presence of train vehicle thereby
ensuring safety in train operation Analog Axle counters on the Indian Railways were introduced
during the 1970s Digital Axle Counters were introduced in early 2000 Digital Axle counters
both Single Section and Multi-Section are installed on Indian Railways due to their wide
applications such as in Station yard Block working IBS Automatic Signalling and Point Zones
Over the years due to technological advancements a number of firms have come up with their
axle counters Following table shows the names of RDSO approved manufacturers and suppliers
of Digital Axle Counters on Indian railways along with the brief description of their model
Although the principle of working is same for all versions of Digital Axle counters their Card
configuration LED indications and parameters are different for different make There may be
more than one type of Digital Axle Counters installed in the section of an SSEJE or Signal
Maintainer hence often he has to refer data of different types of DACs
In view of above an effort has been made to compile the card related information of different
types of Digital Axle Counters mentioned as above in one single document for quick reference
by maintenance personnel This handbook covers brief description of cards their functions and
indications for diagnostics maintenance and important parameters An annexure has also been
added at the end of the handbook which contains relevant data for comparative study

Comparative Study of Cards of different Digital Axle Counters March 2017
व भ न डिजटल ए सल काउटर क काड का तलना मक अ ययन Comparative Study of Cards of different Digital Axle Counters
Introduction Axle Counters play a very important role in detecting the presence of train vehicle thereby
ensuring safety in train operation Analog Axle counters on the Indian Railways were introduced
during the 1970s Digital Axle Counters were introduced in early 2000 Digital Axle counters
both Single Section and Multi-Section are installed on Indian Railways due to their wide
applications such as in Station yard Block working IBS Automatic Signalling and Point Zones
Over the years due to technological advancements a number of firms have come up with their
axle counters Following table shows the names of RDSO approved manufacturers and suppliers
of Digital Axle Counters on Indian railways along with the brief description of their model
Although the principle of working is same for all versions of Digital Axle counters their Card
configuration LED indications and parameters are different for different make There may be
more than one type of Digital Axle Counters installed in the section of an SSEJE or Signal
Maintainer hence often he has to refer data of different types of DACs
In view of above an effort has been made to compile the card related information of different
types of Digital Axle Counters mentioned as above in one single document for quick reference
by maintenance personnel This handbook covers brief description of cards their functions and
indications for diagnostics maintenance and important parameters An annexure has also been
added at the end of the handbook which contains relevant data for comparative study

Comparative Study of Cards of different Digital Axle Counters March 2017
व भ न डिजटल ए सल काउटर क काड का तलना मक अ ययन Comparative Study of Cards of different Digital Axle Counters
Introduction Axle Counters play a very important role in detecting the presence of train vehicle thereby
ensuring safety in train operation Analog Axle counters on the Indian Railways were introduced
during the 1970s Digital Axle Counters were introduced in early 2000 Digital Axle counters
both Single Section and Multi-Section are installed on Indian Railways due to their wide
applications such as in Station yard Block working IBS Automatic Signalling and Point Zones
Over the years due to technological advancements a number of firms have come up with their
axle counters Following table shows the names of RDSO approved manufacturers and suppliers
of Digital Axle Counters on Indian railways along with the brief description of their model
Although the principle of working is same for all versions of Digital Axle counters their Card
configuration LED indications and parameters are different for different make There may be
more than one type of Digital Axle Counters installed in the section of an SSEJE or Signal
Maintainer hence often he has to refer data of different types of DACs
In view of above an effort has been made to compile the card related information of different
types of Digital Axle Counters mentioned as above in one single document for quick reference
by maintenance personnel This handbook covers brief description of cards their functions and
indications for diagnostics maintenance and important parameters An annexure has also been
added at the end of the handbook which contains relevant data for comparative study

Comparative Study of Cards of different Digital Axle Counters March 2017
व भ न डिजटल ए सल काउटर क काड का तलना मक अ ययन Comparative Study of Cards of different Digital Axle Counters
Introduction Axle Counters play a very important role in detecting the presence of train vehicle thereby
ensuring safety in train operation Analog Axle counters on the Indian Railways were introduced
during the 1970s Digital Axle Counters were introduced in early 2000 Digital Axle counters
both Single Section and Multi-Section are installed on Indian Railways due to their wide
applications such as in Station yard Block working IBS Automatic Signalling and Point Zones
Over the years due to technological advancements a number of firms have come up with their
axle counters Following table shows the names of RDSO approved manufacturers and suppliers
of Digital Axle Counters on Indian railways along with the brief description of their model
Although the principle of working is same for all versions of Digital Axle counters their Card
configuration LED indications and parameters are different for different make There may be
more than one type of Digital Axle Counters installed in the section of an SSEJE or Signal
Maintainer hence often he has to refer data of different types of DACs
In view of above an effort has been made to compile the card related information of different
types of Digital Axle Counters mentioned as above in one single document for quick reference
by maintenance personnel This handbook covers brief description of cards their functions and
indications for diagnostics maintenance and important parameters An annexure has also been
added at the end of the handbook which contains relevant data for comparative study

Comparative Study of Cards of different Digital Axle Counters March 2017
व भ न डिजटल ए सल काउटर क काड का तलना मक अ ययन Comparative Study of Cards of different Digital Axle Counters
Introduction Axle Counters play a very important role in detecting the presence of train vehicle thereby
ensuring safety in train operation Analog Axle counters on the Indian Railways were introduced
during the 1970s Digital Axle Counters were introduced in early 2000 Digital Axle counters
both Single Section and Multi-Section are installed on Indian Railways due to their wide
applications such as in Station yard Block working IBS Automatic Signalling and Point Zones
Over the years due to technological advancements a number of firms have come up with their
axle counters Following table shows the names of RDSO approved manufacturers and suppliers
of Digital Axle Counters on Indian railways along with the brief description of their model
Although the principle of working is same for all versions of Digital Axle counters their Card
configuration LED indications and parameters are different for different make There may be
more than one type of Digital Axle Counters installed in the section of an SSEJE or Signal
Maintainer hence often he has to refer data of different types of DACs
In view of above an effort has been made to compile the card related information of different
types of Digital Axle Counters mentioned as above in one single document for quick reference
by maintenance personnel This handbook covers brief description of cards their functions and
indications for diagnostics maintenance and important parameters An annexure has also been
added at the end of the handbook which contains relevant data for comparative study

Comparative Study of Cards of different Digital Axle Counters March 2017
व भ न डिजटल ए सल काउटर क काड का तलना मक अ ययन Comparative Study of Cards of different Digital Axle Counters
Introduction Axle Counters play a very important role in detecting the presence of train vehicle thereby
ensuring safety in train operation Analog Axle counters on the Indian Railways were introduced
during the 1970s Digital Axle Counters were introduced in early 2000 Digital Axle counters
both Single Section and Multi-Section are installed on Indian Railways due to their wide
applications such as in Station yard Block working IBS Automatic Signalling and Point Zones
Over the years due to technological advancements a number of firms have come up with their
axle counters Following table shows the names of RDSO approved manufacturers and suppliers
of Digital Axle Counters on Indian railways along with the brief description of their model
Although the principle of working is same for all versions of Digital Axle counters their Card
configuration LED indications and parameters are different for different make There may be
more than one type of Digital Axle Counters installed in the section of an SSEJE or Signal
Maintainer hence often he has to refer data of different types of DACs
In view of above an effort has been made to compile the card related information of different
types of Digital Axle Counters mentioned as above in one single document for quick reference
by maintenance personnel This handbook covers brief description of cards their functions and
indications for diagnostics maintenance and important parameters An annexure has also been
added at the end of the handbook which contains relevant data for comparative study

व भ न डिजटल ए सल काउटर क काड का तलना मक अ ययन Comparative Study of Cards of different Digital Axle Counters
Introduction Axle Counters play a very important role in detecting the presence of train vehicle thereby
ensuring safety in train operation Analog Axle counters on the Indian Railways were introduced
during the 1970s Digital Axle Counters were introduced in early 2000 Digital Axle counters
both Single Section and Multi-Section are installed on Indian Railways due to their wide
applications such as in Station yard Block working IBS Automatic Signalling and Point Zones
Over the years due to technological advancements a number of firms have come up with their
axle counters Following table shows the names of RDSO approved manufacturers and suppliers
of Digital Axle Counters on Indian railways along with the brief description of their model
Although the principle of working is same for all versions of Digital Axle counters their Card
configuration LED indications and parameters are different for different make There may be
more than one type of Digital Axle Counters installed in the section of an SSEJE or Signal
Maintainer hence often he has to refer data of different types of DACs
In view of above an effort has been made to compile the card related information of different
types of Digital Axle Counters mentioned as above in one single document for quick reference
by maintenance personnel This handbook covers brief description of cards their functions and
indications for diagnostics maintenance and important parameters An annexure has also been
added at the end of the handbook which contains relevant data for comparative study

86 व भ न काड क काय Functions of different Cards
(i) CPU Card (CPU1 amp CPU2) Failsafe 2 out of 2 architecture for controlling and monitoring the SSDAC for
reliable operation Houses the system software that schedules the overall operation as per
configuration
(ii) Phase Detector Card (PD1 amp PD2) A vital card that detects the movement of train axleswheels that is more than
550mm diameter Rejects trolley dolly spoke wheels and push trolley wheels Counts the total number of train axles and updates the system
50 CAMTECHSPROJ16-17HB-CCDAC10
Section VIII G36 GGTronics SSDAC March 2017
(iii) Communication Card (Com1 amp Com2)
Communication between two SSDAC systems is through FSK communication at 1200bps V23 standard along with CRC check
Vital data like axle counts and system status are transmittedreceived between the SSDAC system units
(iv) Relay Drive Card (RD1 ampRD2) Axles sensed by Detector Coils are fed to PD card which in turn feeds signal to
CPU The relay drive card receives instructions from CPU for actuating Vital relay for blocking a section as soon as the first axle is detected It is cleared after both IN and OUT counts of the section match
(v) Power Supply Card Generates required multiple power outputs from 24VDC input
(vi) SM-CPU or Event Logger Card Monitors the SSDAC system and logs vital events during normal and error
operation with date and time stamp As many as 95 different events are recorded Optional display connected to Event Logger Card displays the communication
errors happening in Real-time which aids in assessing the health of communication channel Event logged during normal operation Communication status ok Vital and Preparatory Relay pickup drop Reset operations
Event logged during error operation Communication link fail System down due to failure of any card Vital and Preparatory Relay error status +5 VDC variations Errors

(i) CPU Card (CPU1 amp CPU2) Failsafe 2 out of 2 architecture for controlling and monitoring the SSDAC for
reliable operation Houses the system software that schedules the overall operation as per
configuration
(ii) Phase Detector Card (PD1 amp PD2) A vital card that detects the movement of train axleswheels that is more than
550mm diameter Rejects trolley dolly spoke wheels and push trolley wheels Counts the total number of train axles and updates the system
50 CAMTECHSPROJ16-17HB-CCDAC10
Section VIII G36 GGTronics SSDAC March 2017
(iii) Communication Card (Com1 amp Com2)
Communication between two SSDAC systems is through FSK communication at 1200bps V23 standard along with CRC check
Vital data like axle counts and system status are transmittedreceived between the SSDAC system units
(iv) Relay Drive Card (RD1 ampRD2) Axles sensed by Detector Coils are fed to PD card which in turn feeds signal to
CPU The relay drive card receives instructions from CPU for actuating Vital relay for blocking a section as soon as the first axle is detected It is cleared after both IN and OUT counts of the section match
(v) Power Supply Card Generates required multiple power outputs from 24VDC input
(vi) SM-CPU or Event Logger Card Monitors the SSDAC system and logs vital events during normal and error
operation with date and time stamp As many as 95 different events are recorded Optional display connected to Event Logger Card displays the communication
errors happening in Real-time which aids in assessing the health of communication channel Event logged during normal operation Communication status ok Vital and Preparatory Relay pickup drop Reset operations
Event logged during error operation Communication link fail System down due to failure of any card Vital and Preparatory Relay error status +5 VDC variations Errors

86 व भ न काड क काय Functions of different Cards
(i) CPU Card (CPU1 amp CPU2) Failsafe 2 out of 2 architecture for controlling and monitoring the SSDAC for
reliable operation Houses the system software that schedules the overall operation as per
configuration
(ii) Phase Detector Card (PD1 amp PD2) A vital card that detects the movement of train axleswheels that is more than
550mm diameter Rejects trolley dolly spoke wheels and push trolley wheels Counts the total number of train axles and updates the system
50 CAMTECHSPROJ16-17HB-CCDAC10
Section VIII G36 GGTronics SSDAC March 2017
(iii) Communication Card (Com1 amp Com2)
Communication between two SSDAC systems is through FSK communication at 1200bps V23 standard along with CRC check
Vital data like axle counts and system status are transmittedreceived between the SSDAC system units
(iv) Relay Drive Card (RD1 ampRD2) Axles sensed by Detector Coils are fed to PD card which in turn feeds signal to
CPU The relay drive card receives instructions from CPU for actuating Vital relay for blocking a section as soon as the first axle is detected It is cleared after both IN and OUT counts of the section match
(v) Power Supply Card Generates required multiple power outputs from 24VDC input
(vi) SM-CPU or Event Logger Card Monitors the SSDAC system and logs vital events during normal and error
operation with date and time stamp As many as 95 different events are recorded Optional display connected to Event Logger Card displays the communication
errors happening in Real-time which aids in assessing the health of communication channel Event logged during normal operation Communication status ok Vital and Preparatory Relay pickup drop Reset operations
Event logged during error operation Communication link fail System down due to failure of any card Vital and Preparatory Relay error status +5 VDC variations Errors

(iv) Relay Drive Card (RD1 ampRD2) Axles sensed by Detector Coils are fed to PD card which in turn feeds signal to
CPU The relay drive card receives instructions from CPU for actuating Vital relay for blocking a section as soon as the first axle is detected It is cleared after both IN and OUT counts of the section match
(v) Power Supply Card Generates required multiple power outputs from 24VDC input
(vi) SM-CPU or Event Logger Card Monitors the SSDAC system and logs vital events during normal and error
operation with date and time stamp As many as 95 different events are recorded Optional display connected to Event Logger Card displays the communication
errors happening in Real-time which aids in assessing the health of communication channel Event logged during normal operation Communication status ok Vital and Preparatory Relay pickup drop Reset operations
Event logged during error operation Communication link fail System down due to failure of any card Vital and Preparatory Relay error status +5 VDC variations Errors

86 व भ न काड क काय Functions of different Cards
(i) CPU Card (CPU1 amp CPU2) Failsafe 2 out of 2 architecture for controlling and monitoring the SSDAC for
reliable operation Houses the system software that schedules the overall operation as per
configuration
(ii) Phase Detector Card (PD1 amp PD2) A vital card that detects the movement of train axleswheels that is more than
550mm diameter Rejects trolley dolly spoke wheels and push trolley wheels Counts the total number of train axles and updates the system

Section VIII G36 GGTronics SSDAC March 2017
(iii) Communication Card (Com1 amp Com2)
Communication between two SSDAC systems is through FSK communication at 1200bps V23 standard along with CRC check
Vital data like axle counts and system status are transmittedreceived between the SSDAC system units
(iv) Relay Drive Card (RD1 ampRD2) Axles sensed by Detector Coils are fed to PD card which in turn feeds signal to
CPU The relay drive card receives instructions from CPU for actuating Vital relay for blocking a section as soon as the first axle is detected It is cleared after both IN and OUT counts of the section match
(v) Power Supply Card Generates required multiple power outputs from 24VDC input
(vi) SM-CPU or Event Logger Card Monitors the SSDAC system and logs vital events during normal and error
operation with date and time stamp As many as 95 different events are recorded Optional display connected to Event Logger Card displays the communication
errors happening in Real-time which aids in assessing the health of communication channel Event logged during normal operation Communication status ok Vital and Preparatory Relay pickup drop Reset operations
Event logged during error operation Communication link fail System down due to failure of any card Vital and Preparatory Relay error status +5 VDC variations Errors

86 व भ न काड क काय Functions of different Cards
(i) CPU Card (CPU1 amp CPU2) Failsafe 2 out of 2 architecture for controlling and monitoring the SSDAC for
reliable operation Houses the system software that schedules the overall operation as per
configuration
(ii) Phase Detector Card (PD1 amp PD2) A vital card that detects the movement of train axleswheels that is more than
550mm diameter Rejects trolley dolly spoke wheels and push trolley wheels Counts the total number of train axles and updates the system
50 CAMTECHSPROJ16-17HB-CCDAC10
Section VIII G36 GGTronics SSDAC March 2017
(iii) Communication Card (Com1 amp Com2)
Communication between two SSDAC systems is through FSK communication at 1200bps V23 standard along with CRC check
Vital data like axle counts and system status are transmittedreceived between the SSDAC system units
(iv) Relay Drive Card (RD1 ampRD2) Axles sensed by Detector Coils are fed to PD card which in turn feeds signal to
CPU The relay drive card receives instructions from CPU for actuating Vital relay for blocking a section as soon as the first axle is detected It is cleared after both IN and OUT counts of the section match
(v) Power Supply Card Generates required multiple power outputs from 24VDC input
(vi) SM-CPU or Event Logger Card Monitors the SSDAC system and logs vital events during normal and error
operation with date and time stamp As many as 95 different events are recorded Optional display connected to Event Logger Card displays the communication
errors happening in Real-time which aids in assessing the health of communication channel Event logged during normal operation Communication status ok Vital and Preparatory Relay pickup drop Reset operations
Event logged during error operation Communication link fail System down due to failure of any card Vital and Preparatory Relay error status +5 VDC variations Errors

(i) CPU Card (CPU1 amp CPU2) Failsafe 2 out of 2 architecture for controlling and monitoring the SSDAC for
reliable operation Houses the system software that schedules the overall operation as per
configuration
(ii) Phase Detector Card (PD1 amp PD2) A vital card that detects the movement of train axleswheels that is more than
550mm diameter Rejects trolley dolly spoke wheels and push trolley wheels Counts the total number of train axles and updates the system
50 CAMTECHSPROJ16-17HB-CCDAC10
Section VIII G36 GGTronics SSDAC March 2017
(iii) Communication Card (Com1 amp Com2)
Communication between two SSDAC systems is through FSK communication at 1200bps V23 standard along with CRC check
Vital data like axle counts and system status are transmittedreceived between the SSDAC system units
(iv) Relay Drive Card (RD1 ampRD2) Axles sensed by Detector Coils are fed to PD card which in turn feeds signal to
CPU The relay drive card receives instructions from CPU for actuating Vital relay for blocking a section as soon as the first axle is detected It is cleared after both IN and OUT counts of the section match
(v) Power Supply Card Generates required multiple power outputs from 24VDC input
(vi) SM-CPU or Event Logger Card Monitors the SSDAC system and logs vital events during normal and error
operation with date and time stamp As many as 95 different events are recorded Optional display connected to Event Logger Card displays the communication
errors happening in Real-time which aids in assessing the health of communication channel Event logged during normal operation Communication status ok Vital and Preparatory Relay pickup drop Reset operations
Event logged during error operation Communication link fail System down due to failure of any card Vital and Preparatory Relay error status +5 VDC variations Errors

86 व भ न काड क काय Functions of different Cards
(i) CPU Card (CPU1 amp CPU2) Failsafe 2 out of 2 architecture for controlling and monitoring the SSDAC for
reliable operation Houses the system software that schedules the overall operation as per
configuration
(ii) Phase Detector Card (PD1 amp PD2) A vital card that detects the movement of train axleswheels that is more than
550mm diameter Rejects trolley dolly spoke wheels and push trolley wheels Counts the total number of train axles and updates the system

Section VIII G36 GGTronics SSDAC March 2017
(iii) Communication Card (Com1 amp Com2)
Communication between two SSDAC systems is through FSK communication at 1200bps V23 standard along with CRC check
Vital data like axle counts and system status are transmittedreceived between the SSDAC system units
(iv) Relay Drive Card (RD1 ampRD2) Axles sensed by Detector Coils are fed to PD card which in turn feeds signal to
CPU The relay drive card receives instructions from CPU for actuating Vital relay for blocking a section as soon as the first axle is detected It is cleared after both IN and OUT counts of the section match
(v) Power Supply Card Generates required multiple power outputs from 24VDC input
(vi) SM-CPU or Event Logger Card Monitors the SSDAC system and logs vital events during normal and error
operation with date and time stamp As many as 95 different events are recorded Optional display connected to Event Logger Card displays the communication
errors happening in Real-time which aids in assessing the health of communication channel Event logged during normal operation Communication status ok Vital and Preparatory Relay pickup drop Reset operations
Event logged during error operation Communication link fail System down due to failure of any card Vital and Preparatory Relay error status +5 VDC variations Errors

86 व भ न काड क काय Functions of different Cards
(i) CPU Card (CPU1 amp CPU2) Failsafe 2 out of 2 architecture for controlling and monitoring the SSDAC for
reliable operation Houses the system software that schedules the overall operation as per
configuration
(ii) Phase Detector Card (PD1 amp PD2) A vital card that detects the movement of train axleswheels that is more than
550mm diameter Rejects trolley dolly spoke wheels and push trolley wheels Counts the total number of train axles and updates the system
50 CAMTECHSPROJ16-17HB-CCDAC10
Section VIII G36 GGTronics SSDAC March 2017
(iii) Communication Card (Com1 amp Com2)
Communication between two SSDAC systems is through FSK communication at 1200bps V23 standard along with CRC check
Vital data like axle counts and system status are transmittedreceived between the SSDAC system units
(iv) Relay Drive Card (RD1 ampRD2) Axles sensed by Detector Coils are fed to PD card which in turn feeds signal to
CPU The relay drive card receives instructions from CPU for actuating Vital relay for blocking a section as soon as the first axle is detected It is cleared after both IN and OUT counts of the section match
(v) Power Supply Card Generates required multiple power outputs from 24VDC input
(vi) SM-CPU or Event Logger Card Monitors the SSDAC system and logs vital events during normal and error
operation with date and time stamp As many as 95 different events are recorded Optional display connected to Event Logger Card displays the communication
errors happening in Real-time which aids in assessing the health of communication channel Event logged during normal operation Communication status ok Vital and Preparatory Relay pickup drop Reset operations
Event logged during error operation Communication link fail System down due to failure of any card Vital and Preparatory Relay error status +5 VDC variations Errors

Vital data like axle counts and system status are transmittedreceived between the SSDAC system units
(iv) Relay Drive Card (RD1 ampRD2) Axles sensed by Detector Coils are fed to PD card which in turn feeds signal to
CPU The relay drive card receives instructions from CPU for actuating Vital relay for blocking a section as soon as the first axle is detected It is cleared after both IN and OUT counts of the section match
(v) Power Supply Card Generates required multiple power outputs from 24VDC input
(vi) SM-CPU or Event Logger Card Monitors the SSDAC system and logs vital events during normal and error
operation with date and time stamp As many as 95 different events are recorded Optional display connected to Event Logger Card displays the communication
errors happening in Real-time which aids in assessing the health of communication channel Event logged during normal operation Communication status ok Vital and Preparatory Relay pickup drop Reset operations

Section VIII G36 GGTronics SSDAC March 2017
(iii) Communication Card (Com1 amp Com2)
Communication between two SSDAC systems is through FSK communication at 1200bps V23 standard along with CRC check
Vital data like axle counts and system status are transmittedreceived between the SSDAC system units
(iv) Relay Drive Card (RD1 ampRD2) Axles sensed by Detector Coils are fed to PD card which in turn feeds signal to
CPU The relay drive card receives instructions from CPU for actuating Vital relay for blocking a section as soon as the first axle is detected It is cleared after both IN and OUT counts of the section match
(v) Power Supply Card Generates required multiple power outputs from 24VDC input
(vi) SM-CPU or Event Logger Card Monitors the SSDAC system and logs vital events during normal and error
operation with date and time stamp As many as 95 different events are recorded Optional display connected to Event Logger Card displays the communication
errors happening in Real-time which aids in assessing the health of communication channel Event logged during normal operation Communication status ok Vital and Preparatory Relay pickup drop Reset operations
Event logged during error operation Communication link fail System down due to failure of any card Vital and Preparatory Relay error status +5 VDC variations Errors

Section VIII G36 GGTronics SSDAC March 2017
(iii) Communication Card (Com1 amp Com2)
Communication between two SSDAC systems is through FSK communication at 1200bps V23 standard along with CRC check
Vital data like axle counts and system status are transmittedreceived between the SSDAC system units
(iv) Relay Drive Card (RD1 ampRD2) Axles sensed by Detector Coils are fed to PD card which in turn feeds signal to
CPU The relay drive card receives instructions from CPU for actuating Vital relay for blocking a section as soon as the first axle is detected It is cleared after both IN and OUT counts of the section match
(v) Power Supply Card Generates required multiple power outputs from 24VDC input
(vi) SM-CPU or Event Logger Card Monitors the SSDAC system and logs vital events during normal and error
operation with date and time stamp As many as 95 different events are recorded Optional display connected to Event Logger Card displays the communication
errors happening in Real-time which aids in assessing the health of communication channel Event logged during normal operation Communication status ok Vital and Preparatory Relay pickup drop Reset operations
Event logged during error operation Communication link fail System down due to failure of any card Vital and Preparatory Relay error status +5 VDC variations Errors

Section VIII G36 GGTronics SSDAC March 2017
(iii) Communication Card (Com1 amp Com2)
Communication between two SSDAC systems is through FSK communication at 1200bps V23 standard along with CRC check
Vital data like axle counts and system status are transmittedreceived between the SSDAC system units
(iv) Relay Drive Card (RD1 ampRD2) Axles sensed by Detector Coils are fed to PD card which in turn feeds signal to
CPU The relay drive card receives instructions from CPU for actuating Vital relay for blocking a section as soon as the first axle is detected It is cleared after both IN and OUT counts of the section match
(v) Power Supply Card Generates required multiple power outputs from 24VDC input
(vi) SM-CPU or Event Logger Card Monitors the SSDAC system and logs vital events during normal and error
operation with date and time stamp As many as 95 different events are recorded Optional display connected to Event Logger Card displays the communication
errors happening in Real-time which aids in assessing the health of communication channel Event logged during normal operation Communication status ok Vital and Preparatory Relay pickup drop Reset operations

(i) CPU Card (CPU1 amp CPU2) Failsafe 2 out of 2 architecture for controlling and monitoring the SSDAC for
reliable operation Houses the system software that schedules the overall operation as per
configuration
(ii) Phase Detector Card (PD1 amp PD2) A vital card that detects the movement of train axleswheels that is more than
550mm diameter Rejects trolley dolly spoke wheels and push trolley wheels Counts the total number of train axles and updates the system
50 CAMTECHSPROJ16-17HB-CCDAC10
Section VIII G36 GGTronics SSDAC March 2017
(iii) Communication Card (Com1 amp Com2)
Communication between two SSDAC systems is through FSK communication at 1200bps V23 standard along with CRC check
Vital data like axle counts and system status are transmittedreceived between the SSDAC system units
(iv) Relay Drive Card (RD1 ampRD2) Axles sensed by Detector Coils are fed to PD card which in turn feeds signal to
CPU The relay drive card receives instructions from CPU for actuating Vital relay for blocking a section as soon as the first axle is detected It is cleared after both IN and OUT counts of the section match
(v) Power Supply Card Generates required multiple power outputs from 24VDC input
(vi) SM-CPU or Event Logger Card Monitors the SSDAC system and logs vital events during normal and error
operation with date and time stamp As many as 95 different events are recorded Optional display connected to Event Logger Card displays the communication
errors happening in Real-time which aids in assessing the health of communication channel Event logged during normal operation Communication status ok Vital and Preparatory Relay pickup drop Reset operations
Event logged during error operation Communication link fail System down due to failure of any card Vital and Preparatory Relay error status +5 VDC variations Errors

(i) CPU Card (CPU1 amp CPU2) Failsafe 2 out of 2 architecture for controlling and monitoring the SSDAC for
reliable operation Houses the system software that schedules the overall operation as per
configuration
(ii) Phase Detector Card (PD1 amp PD2) A vital card that detects the movement of train axleswheels that is more than
550mm diameter Rejects trolley dolly spoke wheels and push trolley wheels Counts the total number of train axles and updates the system
50 CAMTECHSPROJ16-17HB-CCDAC10
Section VIII G36 GGTronics SSDAC March 2017
(iii) Communication Card (Com1 amp Com2)
Communication between two SSDAC systems is through FSK communication at 1200bps V23 standard along with CRC check
Vital data like axle counts and system status are transmittedreceived between the SSDAC system units
(iv) Relay Drive Card (RD1 ampRD2) Axles sensed by Detector Coils are fed to PD card which in turn feeds signal to
CPU The relay drive card receives instructions from CPU for actuating Vital relay for blocking a section as soon as the first axle is detected It is cleared after both IN and OUT counts of the section match
(v) Power Supply Card Generates required multiple power outputs from 24VDC input
(vi) SM-CPU or Event Logger Card Monitors the SSDAC system and logs vital events during normal and error
operation with date and time stamp As many as 95 different events are recorded Optional display connected to Event Logger Card displays the communication
errors happening in Real-time which aids in assessing the health of communication channel Event logged during normal operation Communication status ok Vital and Preparatory Relay pickup drop Reset operations
Event logged during error operation Communication link fail System down due to failure of any card Vital and Preparatory Relay error status +5 VDC variations Errors

(i) CPU Card (CPU1 amp CPU2) Failsafe 2 out of 2 architecture for controlling and monitoring the SSDAC for
reliable operation Houses the system software that schedules the overall operation as per
configuration
(ii) Phase Detector Card (PD1 amp PD2) A vital card that detects the movement of train axleswheels that is more than
550mm diameter Rejects trolley dolly spoke wheels and push trolley wheels Counts the total number of train axles and updates the system
50 CAMTECHSPROJ16-17HB-CCDAC10
Section VIII G36 GGTronics SSDAC March 2017
(iii) Communication Card (Com1 amp Com2)
Communication between two SSDAC systems is through FSK communication at 1200bps V23 standard along with CRC check
Vital data like axle counts and system status are transmittedreceived between the SSDAC system units
(iv) Relay Drive Card (RD1 ampRD2) Axles sensed by Detector Coils are fed to PD card which in turn feeds signal to
CPU The relay drive card receives instructions from CPU for actuating Vital relay for blocking a section as soon as the first axle is detected It is cleared after both IN and OUT counts of the section match
(v) Power Supply Card Generates required multiple power outputs from 24VDC input
(vi) SM-CPU or Event Logger Card Monitors the SSDAC system and logs vital events during normal and error
operation with date and time stamp As many as 95 different events are recorded Optional display connected to Event Logger Card displays the communication
errors happening in Real-time which aids in assessing the health of communication channel Event logged during normal operation Communication status ok Vital and Preparatory Relay pickup drop Reset operations
Event logged during error operation Communication link fail System down due to failure of any card Vital and Preparatory Relay error status +5 VDC variations Errors

86 व भ न काड क काय Functions of different Cards
(i) CPU Card (CPU1 amp CPU2) Failsafe 2 out of 2 architecture for controlling and monitoring the SSDAC for
reliable operation Houses the system software that schedules the overall operation as per
configuration
(ii) Phase Detector Card (PD1 amp PD2) A vital card that detects the movement of train axleswheels that is more than
550mm diameter Rejects trolley dolly spoke wheels and push trolley wheels Counts the total number of train axles and updates the system
50 CAMTECHSPROJ16-17HB-CCDAC10
Section VIII G36 GGTronics SSDAC March 2017
(iii) Communication Card (Com1 amp Com2)
Communication between two SSDAC systems is through FSK communication at 1200bps V23 standard along with CRC check
Vital data like axle counts and system status are transmittedreceived between the SSDAC system units
(iv) Relay Drive Card (RD1 ampRD2) Axles sensed by Detector Coils are fed to PD card which in turn feeds signal to
CPU The relay drive card receives instructions from CPU for actuating Vital relay for blocking a section as soon as the first axle is detected It is cleared after both IN and OUT counts of the section match
(v) Power Supply Card Generates required multiple power outputs from 24VDC input
(vi) SM-CPU or Event Logger Card Monitors the SSDAC system and logs vital events during normal and error
operation with date and time stamp As many as 95 different events are recorded Optional display connected to Event Logger Card displays the communication
errors happening in Real-time which aids in assessing the health of communication channel Event logged during normal operation Communication status ok Vital and Preparatory Relay pickup drop Reset operations
Event logged during error operation Communication link fail System down due to failure of any card Vital and Preparatory Relay error status +5 VDC variations Errors

(iii) Communication Card (Com1 amp Com2)
Communication between two SSDAC systems is through FSK communication at 1200bps V23 standard along with CRC check
Vital data like axle counts and system status are transmittedreceived between the SSDAC system units
(iv) Relay Drive Card (RD1 ampRD2) Axles sensed by Detector Coils are fed to PD card which in turn feeds signal to
CPU The relay drive card receives instructions from CPU for actuating Vital relay for blocking a section as soon as the first axle is detected It is cleared after both IN and OUT counts of the section match
(v) Power Supply Card Generates required multiple power outputs from 24VDC input
(vi) SM-CPU or Event Logger Card Monitors the SSDAC system and logs vital events during normal and error
operation with date and time stamp As many as 95 different events are recorded Optional display connected to Event Logger Card displays the communication

86 व भ न काड क काय Functions of different Cards
(i) CPU Card (CPU1 amp CPU2) Failsafe 2 out of 2 architecture for controlling and monitoring the SSDAC for
reliable operation Houses the system software that schedules the overall operation as per
configuration
(ii) Phase Detector Card (PD1 amp PD2) A vital card that detects the movement of train axleswheels that is more than
550mm diameter Rejects trolley dolly spoke wheels and push trolley wheels Counts the total number of train axles and updates the system
50 CAMTECHSPROJ16-17HB-CCDAC10
Section VIII G36 GGTronics SSDAC March 2017
(iii) Communication Card (Com1 amp Com2)
Communication between two SSDAC systems is through FSK communication at 1200bps V23 standard along with CRC check
Vital data like axle counts and system status are transmittedreceived between the SSDAC system units
(iv) Relay Drive Card (RD1 ampRD2) Axles sensed by Detector Coils are fed to PD card which in turn feeds signal to
CPU The relay drive card receives instructions from CPU for actuating Vital relay for blocking a section as soon as the first axle is detected It is cleared after both IN and OUT counts of the section match
(v) Power Supply Card Generates required multiple power outputs from 24VDC input
(vi) SM-CPU or Event Logger Card Monitors the SSDAC system and logs vital events during normal and error
operation with date and time stamp As many as 95 different events are recorded Optional display connected to Event Logger Card displays the communication
errors happening in Real-time which aids in assessing the health of communication channel Event logged during normal operation Communication status ok Vital and Preparatory Relay pickup drop Reset operations
Event logged during error operation Communication link fail System down due to failure of any card Vital and Preparatory Relay error status +5 VDC variations Errors

(iii) Communication Card (Com1 amp Com2)
Communication between two SSDAC systems is through FSK communication at 1200bps V23 standard along with CRC check
Vital data like axle counts and system status are transmittedreceived between the SSDAC system units
(iv) Relay Drive Card (RD1 ampRD2) Axles sensed by Detector Coils are fed to PD card which in turn feeds signal to
CPU The relay drive card receives instructions from CPU for actuating Vital relay for blocking a section as soon as the first axle is detected It is cleared after both IN and OUT counts of the section match
(v) Power Supply Card Generates required multiple power outputs from 24VDC input
(vi) SM-CPU or Event Logger Card Monitors the SSDAC system and logs vital events during normal and error
operation with date and time stamp As many as 95 different events are recorded Optional display connected to Event Logger Card displays the communication
errors happening in Real-time which aids in assessing the health of communication channel Event logged during normal operation Communication status ok Vital and Preparatory Relay pickup drop Reset operations
Event logged during error operation Communication link fail System down due to failure of any card Vital and Preparatory Relay error status +5 VDC variations Errors
