ALLEN BRADLEY 1746-P4 Rockwell Automation Machine Controller Allen Bradley SLC500 1746-P4 Power Supply

1746-P4 SLC 500 Power Supply



The 1746-P4 is an SLC 500 power supply module that provides backplane power to a local chassis, expansion module or a remote I/O chassis. By providing backplane power, the modules attached to chassis slot becomes operable and capable of being recognized by the SLC processor. 

All power supply of the SLC 500 product family features a feature called Hold-up time. Hold-up time refers to the capability of the processor to continue processing logic when the power supply module’s input supply falls below the nominal level. If the power supply continues to experience low voltage level and the hold-up time expires, the processor is stops processing the logic. Normal operation resumes once input voltage returns to normal level.

SLC 500 series A chassis (1746-A4, 1746-A7, 1746-A10, and 1746-A13) manufactured before November 1992 have a resistor between the logic ground and chassis ground as the drawing on the following page illustrates. This resistor could be damaged if the wiring recommendation described within the attention box above is not followed. See the figure on the following page for the location of the resistor. SLC 500 series A chassis (1746-A4, 1746-A7, 1746-A10, and 1746-A13) with a manufacture date of November 1992 or later do not have this resistor. SLC 500 series B chassis have a 1 MΩ resistor that limits the current between logic ground and chassis ground.
