Switch value input, relay output safety barrier (one in two out), the dry contact or NAMUR type proximity switch signal in the dangerous zone, through the isolation output relay contact to the safety zone. You can set the output and input in-phase or inverting logic control (in-phase by default) through DIP switch, and set the line fault monitoring function to be enabled or disabled (by default, the LED flashes when the line fault occurs), and set the second output function (as relay output or as fault alarm output). This product requires independent power supply, and the three terminals of input, output and power supply are isolated.
