SunYuan DIN ISO AC Series Passive 2-wire AC to DC Signal Isolation Transducer is a kind of new isolated conversion devices which can convert ac current or voltage signal into proportional standard analog current signal. The signal transducer can be used with display panel meter or directly connected to the PLC/DCS system to measure or monitor ac current or voltage signal. It is design for the 24VDC and sampling resistance (2-wire meter) 2-wire loop powered circuit, and can be well matched with analog input ports from PCC, DCS, host machine, meters, etc.

DIN ISO AC Series Passive 2-wire AC to DC Signal Isolation Transducer is designed on the high efficient loop powered technique, it operates without power supply, 3KVDC dual isolation between input and output. The loop powered output technique used can simplify the user circuit layout and reduce the cost. It can be directly powered by the signal loop from controlling device, DCS or PLC. The AC to DC Signal Isolation Transducer is widely used in power remote control, automatic equipment, meters, instruments, rail-transit, intelligent equipment,etc.
