The Analogue Input Module provides an interface between RP2 and sixteen analogue plant signals (e.g. Thermocouples, RTD’s, current loops). The board expects a ‘standard’ input range and termination modules are used to match plant signals to this requirement.

Interface Modules
The DIN rail mounted termination modules provide a simple means of interfacing the rack mounted boards to the plant wiring. They also allow the ‘standard’ interface of the board to be ‘tailored’ to the specific plant requirements. The interface to the board is via 4 off 14 way ribbon cables, one for each group of 4 channels. The interface to the plant is via screw terminals capable of accommodating 2.5 mm2 wire and also via a test plug in parallel with the screw terminals.
The available interface modules are:
- Thermocouple Interface Module (CT92783/01)
- Current (Unpowered) Input Interface Module (CT92783/02)
- 4 – 20mA Powered Interface Module (CT92965/01)
- Resistance Temperature Detector (RTD) Interface Module (CT92760/01)
- Ambient Compensation/Thermocouple Interface Module (CT92760/02)
- Starter Motor Interface Module (CT92832/01)
- Starter Motor Interface Module (CT92832/02)
- 10V Input Interface Module (CT94398/01)
- Switch Monitoring Interface Module (CT94570/01)
