Product Description CHINT AI,Isolated Barrier(2 channels)Analogue Input Isolated Barrier,It can provide 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, The product requires independent power supply, power supply, input and output three isolation.Production parameters MODEL NOCB4036-EXNumber of channel2 inputs/2 outputsSupply voltage(Ue)20~35V DCInput signal0~20mA;4~20mA;HARTOutput signal0~20mA;4~20mA;HART;0~5V;1~5VField apparatus2-wire HART transmitter,3-wire transmitter, current sourceTechnical data 1.
