NPEXA-C733

Communication input isolated barrier, it converts the RS-422 digital signals from a hazardous area into RS-422 digital signals to a safe area by isolation, and also provides transmitters with power in the hazardous area. The input, output, and power supply are galvanically isolated from each other.
