ISO 4-20mA-F Dual Loop Powered 4-20mA Isolation Distributor IC contains an electromagnetic coupled converter and current modulate, and a high efficiency DC-DC circuit and so on. The IC supplies to loop distributor 24V, and meets requirements for 4-20mA loop sensor signal measurement, transmission, isolation and so on., it can save energy. The IC output is designed according to Loop circuit power supply of 24VDC and resistance connecting in series, it match to popular module input attachment board, PLC and DCS or the other equipment module input attachment. The internal ceramic PCB, printed impedance and new isolation technologies allow the IC for the 3KVAC insulated voltage and meets the industrial level for the extremely poor temperature, humidity and shaking conditions. ISO 4-20mA-F is easy to use.


If input value is over above range, it may cause permanent damage.
