The WP-9000 series passive DC signal converter (output loop power supply) converts (4-20) mA signals into the required DC signal output through this converter. Mainly used for DCS with input circuit power supply
PLC system.
This converter is powered by a circuit, with complete electromagnetic isolation between the input and output circuits.
