Allen-Bradley 1734-IB8 DC Digital Input Module

The Allen-Bradley 1734-IB8 is an 8-channel digital input module for the POINT I/O family that provides 24V DC sinking inputs. Each of the eight inputs accepts a 24V DC signal from field devices and sinks current to ground, making it ideal for reading discrete signals from sensors and switches in distributed automation systems. Electrical specifications include 8 inputs routed through a single module, 24 V DC input voltage, a maximum of 5 mA input current per channel, a total POINTBus current of 75 mA, and a power dissipation of 1.6 W (about 5.5 BTU/hour). The module is designed to be mounted in a POINT I/O chassis and communicates over the POINTBus, pairing with Rockwell Automation controllers such as CompactLogix and ControlLogix in industrial automation setups. Typical applications involve monitoring digital status from field devices on manufacturing lines, conveyors, and automated equipment where robust 24V DC sensing and reliable isolation within a POINT I/O network are required.
