17.Passive two-wire AC voltage current to DC signal isolation transmitter DIN1×1 ISO NNAC-O1 series
SunYuan DIN ISO AC series passive two-wire AC to DC (AC/DC) signal isolation transmitter is a new detection device that isolates AC current or voltage in linear proportion and outputs standard analog current signals.Use this isolation transmitter to match the corresponding display control instrument or send it to the PLC/DCS system directly, which can realize the measurement and control of AC voltage and current.The output mode of the device is designed for a two-wire power supply circuit connected in series with 24VDC and a sampling resistor (two-wire instrument), which is the same as the current commonly used analog input interface board (host computer), PCC, DCS and on-site display control instrument Match the analog input port.
DIN ISO AC series passive two-wire AC signal isolation transmitter adopts high-efficiency loop power stealing technology, no independent power supply is required, and the input end and the output end can reach 3KVDC isolation.The transmitter adopts a two-wire loop power supply output mode to save two power cords, simplifies the system design scheme, reduces user wiring costs, and can use the display control instrument directly or the signal loop of the DCS/FCS system to provide power.Products are widely used in power remote monitoring, electrical automation, instrumentation, rail transit, industrial control intelligence and other fields.
