Allen-Bradley 1769-IM12 CompactLogix 12-Point 200/240V AC Digital Input Module

Product Description

The 1769-IM12 (1769-IM12) is a high-voltage discrete AC input module designed for Allen-Bradley CompactLogix and MicroLogix 1500 systems. It provides 12 high-voltage input channels (200/240V AC), allowing the controller to safely interface with heavy-duty field devices such as large motor starter auxiliary contacts, high-voltage limit switches, and push buttons.

A key architectural feature of the 1769-IM12 (1769-IM12) is its single-group configuration with a shared internal common. This design significantly reduces wiring complexity and terminal block requirements in high-density industrial control panels. Built for rugged environments, it features robust dielectric isolation between the input side and the backplane bus, ensuring the processor is protected from high-voltage transients. The module is fully compatible with CompactLogix 5370 L1, L2, and L3 controllers and can be integrated into distributed I/O systems via the 1769-AENTR adapter.
