PROBLEM TO BE SOLVED: To provide a control unit of a protection supervisory control panel that allows only a circuit board in a unit mounted on the panel to be exchanged without changing wiring inside the panel when the protection supervisory control panel is exchanged.SOLUTION: In a control unit of a protection supervisory control panel of embodiments, a plurality of circuit boards divides various functions of the control unit of the protection supervisory control panel into sub-functions of input and output, calculation, and communication power supply, and implement a wiring circuit for performing at least one of circuit change of an existing device and function addition, without changing wiring inside the protection supervisory control panel. A mother board is mounted with a system bus to supply power to the plurality of circuit boards and to exchange signals between the circuit boards, and comprises an interface function to pull out the signals outside. A flat cable complements the mother board. A case houses the circuit boards, the mother board, and the flat cable. |
