PRG-1200/1220 output operation terminal isolation safety barrier

PRG-12 port is a 4-20mA output operation end isolation safety barrier that isolates and transmits 4-20mA signals from the safety zone to the hazardous side, driving on-site actuators, valves, and other equipment. This product requires independent power supply, with full isolation between the power supply, input, and output.
