Zusammenfassung:	A relay control apparatus and method for retaining a relay in a closed state even though a system error occurs to reset the processor. Therefore, the relay control apparatus and method prevents an accident caused by the reset of the processor since the operation state of a plurality of relays is maintained even when the processor is reset. In addition, if the operation state of the processor is a reset state even after a predetermined time passes, the operation state of the plurality of relays is changed to a turn-off state, and system resources and energy are prevented from being wasted. In addition, when the operation state of the processor is recovered, the operation state of the plurality of relays may be controlled by the processor.
