Allen-Bradley 1756-PA72 AC Power Supply Module

Allen-Bradley 1756-PA72 ControlLogix AC Power Supply Module is the standard AC input power supply that mounts to the left side of a standard 1756 ControlLogix chassis to energize the backplane and I/O modules. It accepts 85–265 VAC (voltage category 120/240 VAC) at 47–63 Hz and provides a 5 V DC output capable of up to 10 A for the system rails. The module supports Series A and B backplanes and is designed for left-side mounting on 1756 chassis, with common installations noted for use with 1756-A4, 1756-A7, 1756-A10, 1756-A13, and 1756-A17 backplanes. Its physical dimensions are 5.5 in. (W) × 4.4 in. (D) × 5.7 in. (H); it weighs approximately 2.5 lb and operates from 0 to 60 C (32 to 140 F). As part of the ControlLogix power architecture, the PA72 provides the 5 V DC rail necessary for the backplane and logic modules within the chassis.
