Claim 0:
1. A relay control apparatus, comprising:
a processor configured to output 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 monitor connected to the processor to monitor an operation state of the processor and configured to output 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 state determiner configured to receive the first control signal and the second control signal from the processor, receive the retain signal from the monitor, and output 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 received first control signal, the second control signal and the retain signal,
wherein the processor is configured to further output a third control signal for determining the relay control signal output from the relay state determiner, and
wherein the relay state determiner is configured to output 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 received from the processor.
