MVC4 Spare Parts List1-1. Main boardModel: MVC4-CPURating: All ratingsQty Per Unit: 1Description:CPU Board is where the microprocessor and communications co-processor are located.It is attached to the main Power board. The CPU determines operating functions,stores user programming, acts upon feedback signals for faults, and calculatesmetering and historical data. The board communicates with the Keypad OperatorInterface via a serial link cable. Analog and Digital I/O are also located on the CPUboard.- 2 -
