MCR-CP compact passive loop powered isolator provides ground potential isolation of analog control circuits, 0 to 20 mA and 4 to 20 mA. The MCR-CP ensures safe decoupling of the sensor signal from the control electronics.
No external power supply is required for the input or output circuit. The module is powered from the input signal side. The input side loop current is converted to an alternating current signal using a chopper circuit, isolated by a transformer, rectified, and filtered at the output loop.
If the output loop resistance is less than 170 ohms, the input voltage drop is 6.5 V. If the output loop resistance is between 170 ohms and 1000 ohms, the input voltage drop increases linearly from 6.5 to 23.1 V at a loop current of 20 mA.
The output signal is a current source, for a load connected between the (+) and (-) terminals.
