SCM 203 is a current isolator intended for mounting on DIN 35mm rail. It provides galvanic isolation of current sensing loops. Conversion is linear. Connecting of input (4-20mA) and output (4-20mA) current is two way and passive which means that converter is power supplied from current loops. By connecting voltmeter to test connectors it is possible to monitor loop current without interrupting it.
Analog signal conditioners convert, isolate, and amplify signals. SCM203 can convert 4 to 20 mA current signals to standard 4 to 20 mA signals. Also, it can isolate multiple field-measurement devices on a common power supply to help prevent interference that can occur due to ground loops or common-mode noise.
