Abstract

제어시스템의 전원공급회로는 제어대상의 이상 유무를 판단하여 제어대상으로 공급되는 전원을 제어하기 위한 회로이다. 이 회로는 전원입력단자로 유입된 전원의 리플을 제거하고 제어장치로 전원을 공급하는 제1전원장치와, 제어장치의 제어하에 전원입력단자로 유입된 전원에 의해 구동되어 제어대상의 동작에 필요한 동작전원을 공급하는 제2전원장치와, 전원입력단자와 제1전원장치 사이에 접속되어 손으로 눌러 전기접점을 개폐하는 마스타 스위치와, 제어신호 입력단자로 유입된 제어신호에 따라 제어장치에서 제2전원장치로 공급하는 제어신호를 뮤트시킴으로써 제어대상으로 공급되는 공급전원을 차단하는 뮤트수단을 포함하여 제어대상의 이상 발생시 제어대상으로 공급되는 공급전원을 차단할 수 있음으로 인하여 전원공급장치의 에러발생을 없앨 수 있다.The power supply circuit of the control system is a circuit for controlling the power supplied to the control object by determining whether there is an abnormality of the control object. This circuit is driven by the first power supply which removes the ripple of the power introduced into the power input terminal and supplies power to the control device, and the power supplied to the power input terminal under the control of the control device, which is necessary for the operation of the control target. A second power supply for supplying operating power, a master switch connected between the power input terminal and the first power supply to open and close the electrical contact by a hand, and a control device according to a control signal introduced into the control signal input terminal. 2) The occurrence of an error in the power supply device by muting the control signal supplied to the power supply device, by including a muting means for cutting off the supply power supply to the control object, and in the event of an abnormality of the control object, the supply power supplied to the control object can be cut off. Can be eliminated.
