Allen-Bradley 1756-PA72 AC Power Supply Module

The Allen-Bradley 1756-PA72 ControlLogix AC Power Supply is a chassis-mounted power module that delivers 75 watts of backplane power from a 120–240V AC input to a ControlLogix 1756-series chassis and its installed controllers, I/O and communications modules. It is designed to distribute stable power across the ControlLogix backplane to support PLC operation and module interoperability, and it includes LED indicators for power and module status to assist on-site monitoring. Compatible with ControlLogix 1756 chassis, this power supply is suitable for standard industrial control panels powered by facility electrical systems and is commonly used in manufacturing production lines, packaging machinery, conveyors, robotic cells, and process control applications where multiple PLC modules operate within a single chassis. Key specifications include input voltage 120–240V AC, output power 75 W, chassis-mounted form factor, and an operating temperature range of 0°C to 60°C. Common replacements for this module include Allen-Bradley 1756-PA75, 1756-PB72, and 1756-PB75.
