The Allen-Bradley 1746-P4 is a robust and reliable power supply module designed specifically for the SLC 500 series modular chassis. It mounts directly on the left end of the 1746 I/O chassis, providing regulated DC power to the backplane, which in turn powers the processor and all installed I/O modules. This unit accepts a selectable AC input voltage and delivers 10A at 5V DC and 0.96A at 24V DC, ensuring stable and consistent power for demanding industrial automation applications. Its durable construction and proven performance make it an essential component for maintaining the integrity and operation of any SLC 500 control system.
