Allen-Bradley 1734-IB8 Eight Channel Digital Input Module

The Allen-Bradley 1734-IB8 is an eight-channel digital input module for the POINT I/O system that provides 24V DC sinking inputs. It mounts in a compatible 1734 POINT I/O base and communicates on the POINT I/O network, enabling direct connection of sensors to a Rockwell Automation controller. Each of the eight channels accepts a 24V DC input and sinks current, making it suitable for discrete sensors such as pushbuttons, limit switches, and proximity sensors used in industrial automation. Key electricals include a nominal 24V DC input with per-channel input current up to 5 mA and a total POINTBus current up to 75 mA, with a compact power profile of roughly 1.6 W for the module itself. The unit features two green indicators that signal basic power and network status, helping operators verify operation at a glance. Designed for integration with Rockwell controllers in ControlLogix and CompactLogix environments, the 1734-IB8 fits into scalable Point I/O architectures to simplify wiring and software mapping of discrete inputs from multiple field devices.
