Analog isolated barrier, with single-channel analog input and multi-functional output, provide isolated power supply for transmitters in a hazardous area and transfer 4~20mA current signal generated by the transmitter or the current source from hazardous area to a safe area.
This IS barrier type also provides one channel RS-485 output based on MODBUS-RTU protocol and two channels relay output. The RS485 interface can be connected with rail and the power supply can be connected with rail or terminals.
