Allen-Bradley 1769-PA2 CompactLogix AC Expansion Power Supply Module

Product Description

The Allen-Bradley 1769-PA2 (Catalog Number: 1769-L24ER-QB1B) is a high-reliability AC expansion power supply specifically engineered for the CompactLogix and MicroLogix 1500 systems. This module is essential for system architectures where the cumulative current draw of the I/O modules exceeds the capacity provided by the controller's integrated supply. It functions by converting a wide-range AC input (85–265V) into regulated 5V DC and 24V DC backplane power, ensuring stable logic and bus communication across the connected bank.

Designed with industrial-grade durability, the 1769-PA2 is critical for multi-bank configurations. Each I/O bank requires its own power supply, and this module supports up to 8 Compact I/O modules within its physical distance rating. The unit utilizes natural convection cooling, requiring no internal fans, which enhances its longevity in harsh manufacturing environments. Its front-panel status LED provides immediate confirmation of healthy output voltages, simplifying diagnostic procedures during system commissioning or maintenance.
