The isolator is designed to provide isolated DC power to the field transmitter and accept current signal input from the transmitter, as well as current source signal input. After isolation, interference suppression, etc., output standard current or voltage signals to the control system or other instruments.?? Single channel, one input, one output. Input--output--voltage-type magnetic isolation between power supplies.?? Input signal 4~20mA.?? Output signal 4~20mA, 1~5V, or other specified signals.(The output signal is based on the one selected at the time of ordering, see the product label or the data printed on the case).The isolator is powered by a separate DC power supply with a supply voltage range of 20 to 30 VDC.??
