Allen-Bradley 1734-IB8 8-Point Digital Input Module

The Allen-Bradley 1734-IB8 is an 8-channel digital input module for the POINT I/O family, delivering 24V DC sinking inputs that read field signals from sensors and switches. Designed to plug into a POINT I/O chassis, this module accepts eight discrete 24V DC inputs and presents them to the programmable controller as individual digital inputs, enabling straightforward monitoring of industrial signals across a distributed I/O network. As a sinking input module, each channel sinks current from a 24V field device to return the input to ground, making it compatible with common industrial sensors and switches that provide a positive supply. The 1734-IB8 is part of Rockwell Automation's Point I/O lineup, compatible with Rockwell controllers in CompactLogix and ControlLogix ecosystems, and is documented as an eight-channel 24V DC sink input module. Typical applications include machine safety interlocks, limit switch arrays, presence sensors, and other distributed sensing tasks where eight digital inputs are required in a compact, modular package.
