Allen-Bradley 1769-PA4 CompactLogix AC Power Supply Module
Allen-Bradley 1769-PA4 is a CompactLogix 1769 Compact I/O AC power supply module that delivers 4 A at 5 V DC and 2 A at 24 V DC from a 120/240 V AC input (85…265 V AC operating range, 47…63 Hz). It dissipates a maximum of 18 W at 60 °C, powers up to 8 Compact I/O modules on each side (16 total), and mounts on a DIN rail or panel — the high-capacity power option for CompactLogix 1769 systems.
Overview
The 1769-PA4 belongs to the Allen-Bradley CompactLogix 1769 Compact I/O family. It connects directly to the Compact I/O bus beside the controller or an expansion power supply — no connection cables needed — and shares the same DIN-rail footprint and Studio 5000 (RSLogix 5000) engineering environment as the rest of the 1769 line.

Applications
The 1769-PA4 is the standard AC power supply for CompactLogix 1769 systems that need extra 5 V and 24 V capacity — typical for larger local I/O banks, mixed digital/analog configurations, and systems with specialty modules. It plugs directly into the Compact I/O bus and requires no connection cables.
