Allen-Bradley 1791D-N4CV2X is a CompactBlock I/O expansion module for DeviceNet that provides four DC input channels and two analog output channels, designed to extend a compatible CompactBlock base I/O assembly. The module is powered through the base I/O assembly on a 24 V DC supply and carries a documented input current rating of 100 mA for the expansion I/O. In DeviceNet networks, the 1791D-N4CV2X configuration supports a 4-in/2-out footprint, enabling remote sensing of field devices and basic analog output control for automation applications.
