Abstract
A relay control device according to one aspect of the present invention includes: a processor configured to output a basic control signal for controlling the operation of a relay and a first decision control signal having a signal level such as a difference depending on its own operating state; a monitoring unit configured to monitor the operating state of the processor and output a second decision control signal having a signal level such as a difference depending on the operating state of the processor, and a retain signal for maintaining the operating state of the relay; and a relay state determination unit configured to output either the basic control signal or the retain signal as a relay control signal for controlling the on / off state of the relay, based on the signal levels of the first decision control signal and the second decision control signal.
