4-20mA Current Loop for ISO 4-20mA-F (SIP12 Pin) and ISOS 4-20mA-F (SIP7 Pin Package)Signal isolation amplifierIt is an isolation module powered by a two-wire circuit. By using the back-end power supply method, the front-end two-wire equipment is powered and receives a 4-20mA current signal output from the two-wire equipment. After module isolation, the 4-20mA current signal is output to the sensor for operation. This scheme adopts electromagnetic isolation mode and high-efficiency post stage feeding technology, effectively solving the problem of dependence on power supply for current signal isolation, achieving precise isolation and transmission of standard signal 4-20mA, and can be matched with various instrument two-wire circuit power supply analog input ports (such as PLC, DCS system, etc.).
