GS8531-EX  AI,Isolated Barrier(1 channel,Loop powered)

Analogue input, output isolated barrier with loop-powered: provides the transmitter located in the hazardous area a separate power, transfer current signal generated by transmitter from a hazardous area to a safe area, can also transfer current signal from a safe area to a hazardous area and drive equipments like actuator in field. It allows bi-directional transmission of HART communication signals, and is suitable for using loop-powered DCS, PLC systems.
