Abstract

PURPOSE:To execute the protection coordination of an element, by switching it by on and off signals which are outputted from an operation processing equipment, making an emergency stop of the element take precedence by an output signal from an analog detecting circuit, and executing the postprocessing by the operation processing equipment. CONSTITUTION:A countermeasure program relating to a fault of a main circuit is stored in advance in a microcomputer 10, and this circuit is constituted so that a logical circuit 14 and a gate circuit 16 are made a start ready state or a stop state, and the present status is maintained until the external condition is varied, in accordance with said program. The gate circuit 16 transmits a signal from the microcomputer 10 to the base of a transistor TR through an amplifying circuit 18 in accordance with a logical output from the logical circuit 14, and makes the transistor TR execute a switching operation.
