S7-300 Module Data - Analog IO Module SM 334

Analog IO module SM 334; AI 4/AO 2 x 8/8 Bit; (6ES7334-0CE01-0AA0)

Order number6ES7334-0CE01-0AA0

Properties

• 4 inputs in one group and 2 outputs in one group

• Resolution 8 bits

• Programmable measurement type at each channel group

― Voltage

― Current

• Not programmable, measurement and output type defined by hardwiring

• Connected to potential of the backplane bus interface

• Electrically isolated to load voltage

Terminal assignmentThe diagrams below show various wiring options.

Note

Note when wiring the SM 334:

• analog ground MANA(terminal 15 or 18) is interconnected with chassis ground M of the CPU orinterface module IM. Use a cable with a conductor cross-section of at least 1 mm2.

The module will shut down if the ground connection between MANA and M is missing. Inputs are readwith 7FFFH, and outputs return a value of 0. The module may be destroyed if operated without groundover a longer period of time.

• the supply voltage for the CPU and/or the interface module (IM) may not be connected with reversedpolarity. Reverse polarity will inevitably lead to the destruction of the module, because MANA developsan impermissible high potential (+24 V.)
