AC to 4-20mA Two-Wire Passive Isolated Signal Transmitter

SunYuan DIN ISO AC series passive two-wire AC to DC (AC/DC) signal isolation transmitter is a new type of detecting device that isolates and transmits standard analog current signals from AC current or voltage in linear proportion .With this isolation transmitter with the corresponding display and control instruments or directly to the PLC/DCS system, so that the measurement and control of AC voltage and current can be realized. The output of the device is designed for a two-wire power supply loop with 24VDC and sampling resistors (two-wire instrumentation) in series, which is compatible with the analog input ports of current analog input interface boards (host computers), PCCs, DCSs, and on-site display and control instruments.  

      DIN ISO AC series passive two-wire AC signal isolation transmitter adopts high-efficiency loop-stealing technology, no need for independent power supply, the input and output can reach 3KVDC isolation. The transmitter adopts two-wire loop power supply and output mode to eliminate two power cables, which simplifies the design of the system and reduces the wiring cost of the user, and can be used directly to provide power to the signal loop of the display and control instrument or DCS/FCS system. The products are widely used in electric power remote monitoring, electrical automation, instrumentation, rail transportation, industrial control intelligentization and other fields.
