Beschreibung
Zusammenfassung:	A relay control apparatus and method according to an embodiment of the present disclosure is capable of retaining a relay in a closed state even though a system error occurs to reset the processor. Therefore, the relay control apparatus and method according to an embodiment of the present disclosure has an advantage of preventing 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 thus there is an advantage of preventing system resources and energy from being wasted. In addition, when the operation state of the processor is recovered, there is an advantage in that the operation state of the plurality of relays may be controlled by the processor.
