Allen-Bradley 1791-IOBW 64-Point DC Input Module

The Allen-Bradley 1791-IOBW is a 64-point DC input module for the 1791 Flex I/O system that reads 24V DC signals into a Rockwell Automation controller. It provides 64 independent input points that connect to field devices such as sensors, pushbuttons, and limit switches, enabling distributed digital inputs across an automation network. The module plugs into a compatible 1791 I/O bus/backplane and is scanned by the PLC to deliver per-point status, supporting scalable I/O configurations for small to mid-size automation applications. With 24V DC input compatibility, the 1791-IOBW is designed for environments where numerous binary signals must be monitored simultaneously, including machine state sensing, safety interlocks, and process condition monitoring. Typical use cases include manufacturing lines, packaging operations, and material handling systems where reliable, centralized monitoring of many 24V inputs is required.
