The Allen Bradley SK-R1-MCB1-PF755 is a PowerFlex 755 Main Control Board Kit, Series A, used as the primary control electronics for Rockwell Automation PowerFlex 755 AC drives. This main control board is compatible with PowerFlex 755 wall mount frame sizes 1 through 7 across voltage classes C, D, E, and F. Device power requirements indicated on the label are 12V DC at 505 mA and negative 12V DC at 22 mA. The board ships from the factory with firmware version V 11.001 as noted on the original label. Serial number 204AE56E is recorded on the factory label, with a manufacturing date of 2014/12/19. The unit is supplied in its original Allen Bradley factory sealed packaging with the PN 41258 carton identifier and UPC 884951095397. This main control board manages drive logic, communication, diagnostics, and motor control functions within the PowerFlex 755 drive platform and is compatible with Rockwell Studio 5000 programming software. The catalog number SK-R1-MCB1-PF755 has been discontinued by Rockwell Automation as of December 30, 2024, with SK-R1-MCB2-PF755 listed as the direct replacement. This unit remains a viable spare for installed PowerFlex 755 systems that require the original Series A main control board for compatibility with existing firmware or hardware configurations.
