Allen-Bradley 1734-1B8 IO Digital Input Module

The Allen-Bradley 1734-IB8 POINT I/O 8-Channel Digital DC Input Module provides eight 24V DC sinking input points for distributed control networks. This DIN-rail mounted module slots into a POINT I/O network and is designed to mount with terminal bases such as 1734-TB, 1734-TBS, or compatible 1734-TOP/1734-TOPS bases, enabling flexible enclosure configurations. As part of the POINT I/O family, the 1734-IB8 reads discrete digital signals from field devices—sensors, switches, and other 24V components—into Rockwell Automation PLCs, including CompactLogix and ControlLogix systems, with configuration mapped in the Studio 5000/Logix Designer environment. The module is explicitly described as a 24V DC 8-channel sink input module, delivering eight individual input channels that integrate with the POINT I/O bus for scalable, distributed I/O. Its compact form and point-to-point wiring reduce panel clutter while preserving robust diagnostics and seamless integration within the Rockwell ecosystem. Typical applications include remote sensing of conveyors, machine controls, packaging lines, and automation panels where reliable 24V sensing and straightforward I/O expansion are required.
