Title: (KO) 인버터의 단자 회로
(EN) TERMINAL CIRCUIT IN INVERTER
Abstract:
(KO) 인버터의 단자 회로가 개시된다. 본 발명의 회로는, 입출력 신호를 전기적으로 절연하며, 입력으로서 제1포트로부터 오픈 컬렉터 출력신호 또는 펄스 출력신호를 수신하여, 제1출력으로서 제2포트로 출력하는 포토커플러, 포토커플러의 제2출력에 베이스(B)가 연결되는 트랜지스터, 및 트랜지스터의 베이스(B)와 이미터(E)에 연결되는 바이어스 저항을 포함한다.
(EN) Disclosed is a terminal circuit in an inverter. The circuit according to the present invention includes: a photocoupler which electrically insulates an input-output signal, receives an open collector output signal or a pulse output signal from a first port as an input, and outputs the received output signal to a second port as a first output; a transistor whose base (B) is connected to a second output of the photocoupler; and a bias resistance is connected to the base (B) and an emitter (E) of the transistor.
