CMA Interface modules decouple sensors on the input side and actuators on the output side of control systems and enable the manipulation of measured and actuating values. This function is crucial for commissioning, troubleshooting, manual emergency operation or wherever intervention is required. The various switch positions of ON/OFF/AUTO or MAN/OFF/AUTO allow the input signal to be transmitted to the output unaltered or manually altered. The two analogue value transmitters are available for the standard signals 0 – 10 V and 0 – 20 mA in accordance with EN 60381.
The «feedback loop» represents the switch position and can be analysed by the control system. The changeover contact of the feedback is closed in automatic mode so that it results in a logical 1 on the control unit. Several feedback signals can be connected in series.
