Product description

The Allen-Bradley 1746-P4 is a rack-mounting power supply module designed for the SLC 500 system. It provides essential backplane power to the local chassis, expansion modules, or remote I/O chassis, enabling attached modules to operate and be recognized by the SLC processor. This power supply accepts a wide input voltage range of 85-132V AC or 170-265V AC at 47-63 Hz and delivers a 24V DC output.

This power supply is crucial for the operation of SLC 500 controllers, supporting various digital and analog I/O modules, communication modules, and other system components. It is commonly found in applications requiring robust and reliable PLC control, such as manufacturing automation, material handling, and process control.
