The Allen-Bradley 1746-P1 is a reliable and robust power supply module designed specifically for the SLC 500 series of programmable logic controllers. It mounts directly on the left side of any 1746 I/O chassis, converting 85-132V AC line power into the necessary DC voltages required by the SLC 500 processor and I/O modules on the backplane. This unit provides 2A of current at 5V DC and 0.46A at 24V DC, ensuring stable and consistent power for small to medium-sized control applications. Its straightforward installation and proven performance make it an essential component for maintaining the integrity and operation of your SLC 500 system.
