ISCM Allegro A31312 (C27)

The CompactRIO module “Intelligent Sensor Calibration Module” (C27) developed by CGS can program and calibrate up to 2 Allegro A31312 sensors in parallel. In addition, the module can read the data via SENT and PWM on channel 1A and 2A in parallel. This is also possible if the sensors output their data via different protocols, e.g. sensor 1 uses SENT and sensor 2 uses PWM. Channels 1B and 2B are a digital inputs and can read the switch output provided by the sensor.

The computing power for the complex programming routine and SENT decoding is provided by an FPGA installed in the module. The FPGA of the CompactRIO chassis is only used for communication with the CGS module. This allows up to 8 intelligent modules per chassis to be operated. The module is available for calibrating different sensors from several manufacturers. A list of supported sensors can be sent on request. The ISCM supports the SENT standards SAE J2716. The sensors are powered thru the cRIO module, connected to an external power supply (10-36 V, not included).
