Allen-Bradley 1734-IB8 8 Channel 24V DC Input Module

Allen-Bradley 1734-IB8 is an eight-channel 24V DC input module for the POINT I/O family. It provides eight discrete digital inputs that sink 24V DC signals; each channel draws up to 5 mA, with a total POINTBus current of up to 75 mA, and it dissipates roughly 1.6 W. This module communicates with Rockwell Automation controllers over the POINT I/O bus, enabling scalable input expansion for CompactLogix and ControlLogix systems. With eight inputs, it supports monitoring of eight sensors or switches—such as proximity sensors, limit switches, or door interlocks—in a single card, simplifying panel wiring and layout. The sink input configuration means field devices source the 24V DC supply while the module sinks current through the input channels to the common, making it a straightforward fit for standard 24V DC automation circuits. Designed for POINT I/O backplane configurations, the 1734-IB8 integrates into Rockwell’s modular I/O strategy to extend digital input capacity in existing automation architectures.
