The Allen-Bradley 1791-16B0 is a 16 Input DC Block I/O Module designed for distributed input monitoring through Allen-Bradley Remote I/O (RIO) networks. It provides 16 inputs arranged in two groups of eight, supports standard 24 VDC field signals, and offers selectable fast or slow input filtering for different application requirements. With multiple RIO communication rates, electrical isolation, built-in protection, and comprehensive status indication, the module enables reliable acquisition of signals from sensors, switches, pushbuttons, limit switches, and other discrete field devices. It is well suited for machinery, manufacturing lines, material handling, and legacy Allen-Bradley PLC and SLC-based automation systems.
Compared with conventional distributed DC input modules, the Allen-Bradley 1791-16B0 combines flexible input filtering, direct Remote I/O connectivity, reliable electrical isolation, and straightforward integration with legacy Allen-Bradley control systems.
