The 1769-IM12 (Part Number: 1769-IM12) is a high-voltage digital AC input module designed for Allen-Bradley CompactLogix and MicroLogix 1500 systems. This module provides twelve isolated inputs capable of interfacing with 240V AC field devices, such as limit switches, pushbuttons, and motor starter auxiliary contacts. It is an essential component for industrial applications where high-voltage AC control circuits are standard, allowing the PLC to safely monitor the status of high-power equipment.
Engineered for reliability in harsh electrical environments, the 1769-IM12 features built-in hardware filtering to prevent false triggering from electrical noise. The module's robust design includes a signal delay of 20 milliseconds to ensure stable state transitions. As part of the 1769 series, it utilizes a removable terminal block (RTB) to simplify installation and maintenance, allowing for module replacement without disturbing the field wiring.

The 1769-IM12 is typically used in heavy industrial environments, utility stations, and large-scale manufacturing plants where 240V AC control power is preferred over 24V DC. It is ideal for monitoring legacy machinery, long-distance sensor runs where voltage drop is a concern, or interfacing with power distribution equipment.
Can this module be used with 120V AC signals?
No, the 1769-IM12 is specifically rated for 200–240V AC. Its minimum ON-state voltage is 159V AC, meaning a 120V signal will not be recognized by the module. For 120V AC applications, the 1769-IA8 or 1769-IA16 should be used instead.
Does the module require a separate power supply for the inputs?
The 240V AC power for the inputs must be provided by an external field power source. The module only draws logic-side power (100 mA) from the CompactLogix backplane.
