Product Overview
The Allen-Bradley 1791D-16B0X is a CompactBlock I/O expansion module providing sixteen sinking discrete inputs via DeviceNet. It extends the I/O capacity of CompactBlock stations and integrates into DeviceNet control networks. Typical use includes distributed input expansion in cabinet-mounted automation systems controlled by PLC-2, PLC-3, PLC-5, SLC-500 or SoftLogix scanners. 1791D-16B0X supports modular expansion up to 32 points.
