Product Isolated Barrier NPEXA-H511

NPEXA-H511

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