Allen-Bradley | 1746-P1 | SLC 500 (1746 Series)

Product Description: Allen-Bradley 1746-P1

The Allen-Bradley 1746-P1 is an AC-input power supply module specifically designed for the 1746-A4 (4-slot) chassis in the SLC 500 modular PLC system. It provides essential backplane power to support processor, I/O, and communication modules within the chassis. With auto- switching 120/240V AC input and regulated 5V/24V DC outputs, the 1746-P1 offers compact, reliable power delivery for small control systems.
