Allen-Bradley | 1746-P2 | SLC 500 (1746 Series)

Product Description: Allen-Bradley 1746-P2

The Allen-Bradley 1746-P2 is a standard AC-input power supply module used in the SLC 500 modular PLC platform. It mounts directly on the left end of a 1746 chassis and provides the required backplane power to operate processor, I/O, and communication modules. Designed for global compatibility, it accepts a wide AC input voltage range and delivers both 5V DC and 24V DC outputs, making it suitable for a broad range of industrial applications.
