Allen-Bradley 1734-IV4 Digital Input Card Module

The Allen-Bradley 1734-IV4 is a POINT I/O digital input module that provides four 24 V DC sourcing inputs for a POINT I/O network. Designed for open-style, DIN‑mounted installation, it accepts field-wired digital signals from sensors and switches and feeds them to a Rockwell Automation programmable controller via the POINT I/O basebackplane. Each of the four channels operates independently to register discrete on/off states, enabling straightforward ladder logic or function block processing for typical industrial automation tasks. This module is used to interface devices such as pushbuttons, limit switches, proximity sensors, and other 24 V DC sensing equipment, making it a compact and scalable solution for distributed I/O in manufacturing lines, packaging, material handling, and automated processing cells. As part of the POINT I/O family, the 1734-IV4 integrates with compatible controllers and software for configuration, diagnostics, and seamless integration with other 1734 modules (outputs, analog I/O, and higher-channel digital options) to build flexible, space-efficient control architectures. Cataloged as a four-point digital input module with 24 V DC sourcing, the 1734-IV4 is ideal when you need reliable real-time status from multiple sensors in a compact, modular format.
