Allen-Bradley 1746-P4 SLC 500 Power Supply Module

The Allen-Bradley 1746-P4 SLC 500 Power Supply Module provides regulated backplane power for an SLC 500 chassis from a 24 V DC input, energizing CPUs, communication modules, and I/O cards in industrial control panels, manufacturing systems, and process automation equipment. Designed for chassis-mounted installation on the left side of 1746 SLC 500 racks, it delivers the necessary backplane power to support reliable operation of legacy SLC platforms. Manufactured by Allen-Bradley (Rockwell Automation), this PLC power supply is specifically the 1746-P4 model for SLC 500 systems, with output capacity described as application dependent. Compatible with 1746 SLC 500 racks, it is suited for industrial environments where stable PLC backplane power is essential for continuous automation performance.
