Product Overview
The Allen-Bradley 1769-IM12 is a 12-point AC input module designed for CompactLogix systems. It accepts 240V AC inputs with a signal delay of 20 milliseconds, making it ideal for upgrading older I/O racks or building new automation lines. As part of the Compact I/O family, this module offers a compact footprint and straightforward integration.

Common Applications
The 1769-IM12 serves in packaging lines, material handling, and batch processing where 240V AC sensors or limit switches must be interfaced to a CompactLogix controller. Its 12-point density fits medium-size I/O groups, and the 20 ms delay filters out electrical noise common in industrial environments.
Installation and Setup
Mount the module on a DIN rail or panel using the 1769-RTBN18 terminal block. Use copper wiring rated for 90°C, and observe the 8-module distance rating when connecting the power supply. Secure all connections with the provided screws. No special tools are required beyond a standard screwdriver.
Selection and Purchasing Advice
Verify your system voltage (240 VAC line-to-line or line-to-neutral) and that the input devices meet the 159 VAC minimum ON-state. The 1769-IM12 replaces earlier fixed I/O modules and integrates directly with CompactLogix controllers. For reliable supply, choose UBEST Automation as your partner.
