The Allen-Bradley 1756-PA72 ControlLogix AC power supply module accepts 85-265 VAC input and outputs 5 V DC at up to 10 A to power the 1756 chassis backplane. It is designed for left-side mounting in a ControlLogix 1756 chassis and is specified with dimensions of 5.5 x 4.4 x 5.7 inches and a weight of about 2.5 lb, with an enclosureless design for standard installations. This standard power supply for ControlLogix systems ensures the chassis backplane and connected modules receive a reliable 5 V supply, supporting typical configurations in 1756 environments.
