Abstract

PURPOSE: To decrease the number of component parts of the titled protecting circuit by providing an action discriminating resistance which is changed to the negative resistance value to an inactive signal which has the fixed resistance value to an active signal of a pulse wave given from an electronic controller and is not equal to a pulse wave and therefore actuating a device to be controlled when the resistance value of said action discriminating resistance is kept at a fixed level.
CONSTITUTION: An electromagnetic relay R, etc. of a device B to be controlled are actuated by a programmed sequence given from an output circuit of a microcomputer A. An action discriminating resistance NTC is provided to a protection circuit for electronic controller set between the computer A and the device B. Then the continuous waves are applied to the NTC from an FETa of an output circuit via a resistance Ra. The resistance value is kept at an approximately fixed level by the NTC to an action signal produced by a pulse wave. The resistance value is changed to the negative side to an inactive signal which is not equal to a pulse wave. A transistor TRQa is actuated when the resistance value of the NTC is kept at an approximately fixed level. Thus the number of parts is decreased for an action protecting circuit and the actuation of this circuit is stabilized.
