Switching value input (one in and one out), the transistor outputs safety barrier, and outputs the dry contact or NAMUR-type proximity switch signal in the dangerous zone to the safe area transistor output through isolation. 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.
