Allen-Bradley 1734-IV8 POINT I/O 8-Channel DC Sourcing Module

Product Description

The Allen-Bradley 1734-IV8 is a POINT I/O digital input module from Rockwell Automation’s Bulletin 1734 family, designed for reliable monitoring of discrete DC signals. This module provides eight 24 V DC sourcing input channels, ideal for interfacing with field devices such as push buttons, limit switches, sensors, and other devices with sourcing logic.

Compact and DIN-rail mountable, the 1734-IV8 integrates seamlessly into distributed I/O systems, reducing wiring complexity and supporting scalable automation architectures via POINT I/O adapters. Unlike sinking input modules (e.g., 1734‑IB8), the IV8 sourcing module is tailored for applications where field devices provide a grounded return path.
