Classification: CPC B  H | IPC B  H

Claim 10:
11. A relay control method, comprising:
a first signal output step of, by a processor, outputting a first control signal for controlling an operation state of a first relay and a second control signal for controlling an operation state of a second relay;
a second signal output step of, by a monitor, connecting the monitor to the processor to monitor an operation state of the processor and outputting a retain signal for maintaining the operation states of the first relay and the second relay according to the operation state of the processor; and
a relay control signal output step, by a relay state determiner, outputting a first relay control signal for controlling the operation state of the first relay and a second relay control signal for controlling the operation state of the second relay based on the first control signal, the second control signal and the retain signal,
wherein after the second signal output step, the relay control method further comprises a third signal output step of, by the processor, outputting a third control signal for determining the relay control signal output in the relay control signal output step, and
wherein the relay control signal output step is a step of outputting a part of the first control signal, the second control signal and the retain signal as the first relay control signal and the second relay control signal, based on a signal level of the third control signal.
