• Measurement values from the preceding MAI modules are read via the SPI bus.

• Automatic presetting of the bridge current, zero point and sensitivity in passive sensors with

MPI module through the SPI-Bus (possible only in connection with MDA20)

• Measurement signals are processed in 100-ms cycles; the mean value is calculated over a

period of 1 sec.

• Data is transmitted to the MCP module over the CAN bus.

• All supply voltages are monitored (EXT, INT and BAT) and sent to the MCP for evaluation.

• System Failure relay is activated when a processor error occurs.

• Euro card with a 96-way connector.

Description

This module accepts the measurement values generated by the preceding Analog Input modules

(MAI modules), of which there can be a maximum of 8. This provides the signal processing and

calculation for a maximum of 64 sensors and the results are passed to the MCP module via the

CAN bus.
