Claims (1)

  1. 병렬로 접속된 복수개의 접점과, 이 각접점에 직렬로 접속되고 입력신호에 따라서 동작하는 게이트(gate)소자와, 상기의 접점과 게이트 소자를 포함하는 회로에 접속된 출력소자가 있으며, 상기 접점과 게이트 소자와를 결합시켜서 상기의 접점에 나타나는 ON/OFF 정보를 상기의 출력 소자를 통하여 전달하게 한 디지탈입력 회로에서 교류를 전파 정류한 것을 상기의 접점회로에 공급하고 또 상기의 출력단자의 출력을 상기전파 정류의 맥류에 동기시킨 것을 특징으로 하는 디지탈 입력 회로.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
