Product Description
PRG-2000 detection end/operation end isolated safety barrier, channel one transmits standard 4mA~20mA current signal from the safety side to the danger side, driving the on-site actuator to work. Channel 2 provides a 24V isolated DC power supply from the safe area to the hazardous area for a two-wire transmitter. The transmitter generates a 4mA to 20mA current signal that is isolated from the hazardous area and transmitted to the safe side output (or converted to a 1V to 5VDC output). This product requires independent power supply (fully isolated between power supply, input, and output)
