NPEXA-C512

Digital input isolated barrier, it converts switch or proximity detector signals (dry contact or NAMUR) from a hazardous area into transistor signals to a safe area by isolation. The normal output sate and line fault detection function can be set with the DIP switch. The input, output, and power supply are galvanically isolated from each other.
