Two-in and two-out read analog input, output isolator (dual-mode), can provide isolated power for on-site two-wire system intelligent (HART) transmitter, and isolate the 4-20mA signal generated by the transmitter, the 4-20mA signal generated by the control room can also be isolated and output to drive the on-site actuator. 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. CZ3032 provides isolator of power for the loop, without independent power supply, and has reverse power protection function.
