Isolated safety barrier/two_in and two_out read analog input, output isolated safety barrier [loop power supply]

Read analog input. Output separation fence. It can not only provide isolated power to the transmitter in the dangerous area, transmit the current signal generated by the transmitter from the dangerous side to the safe side, but also transmit the current signal from the safe side to the dangerous side, drive on-site actuators and other equipment. At the same time, it supports bidirectional transmission of HART digital signals and is suitable for DCS, PLC and other systems with loop power supply.
