Allen-Bradley 1734-IB4 4-Channel Digital Input Module

Allen-Bradley 1734-IB4 is a four-channel 24V DC sinking digital input module for the POINT I/O family. It offers four discrete inputs with a common return, designed to sense 24V DC signals from field devices such as pushbuttons, limit switches, and proximity sensors. The module is intended for DIN-rail mounting and is compatible with POINT I/O networks that use the 1734 series, enabling scalable I/O expansion with minimal wiring. With its compact four-channel footprint, the 1734-IB4 supports digital input density for applications like conveyor control, machine control panels, and general-purpose sensing that requires a 24V DC input. For diagnostic capabilities, see the 1734-IB4D variant; otherwise, this non-diagnostic version provides straightforward, reliable 24V DC input sensing in industrial environments.
