Abstract
An electronic controller includes an internal power stabilizing circuit which supplies stabilized power to drive circuits and a fail-safe relay drive circuit all built within the controller, a monitoring unit which monitors the operational states of the circuits in the controller based on the state of power output of the power stabilizing circuit, and a drive unit which drives the fail-safe relay drive circuit in response to the detection by the monitoring unit of a predetermined output state of the power stabilizing circuit indicative of the occurrence of abnormality in at least one of the circuits including the drive circuits within the controller.
