Isolated safety barrier

Switch value input, relay output safety barrier (one in one 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 use DIP switch to set the output and input in-phase or inverting logic control (the default in-phase), and set the line fault monitoring function to be enabled or disabled (the default is enabled, and the LED flashes when the line fault occurs). This product requires independent power supply, and the three terminals of input, output and power supply are isolated.
