BUR MCPEAB-1 PEA42 Printed Circuit Board

BUR MCPEAB-1 PEA42 Printed Circuit Board is a two-circuit PLC circuit board used as a repair or replacement part in legacy control systems. The board is identified by the MCPEAB-1 and PEA42 designators and is sometimes described in listings as PEA4/2, signaling its dual-circuit configuration. As a used PLC PCB, it is commonly sold as a spare part for automation equipment to restore or extend the life of older BUR/Rockwell control installations. The exact electrical characteristics, connector layout, and socket compatibility depend on the original controller family and chassis—buyers should match the OEM documentation for the specific machine or panel before attempting installation. The MCPEAB-1 PEA42 board enables dual independent circuit paths on a single PCB, which can facilitate modular expansion or replacement of a failed dual-channel module without replacing the overall controller.
