Abstract

본 발명은 PLC와 같은 자종 제어기 (전기, 전자기기)의 입.출력부에 접속되는 전기장치(actuator 또는 device)와 광 스위치(optical switch)를 블록화 또는 일체화시켜 광 제어장치(OFCR)를 구성함으로써 전기적인 신호가 아닌 광파이버 (optical fiber 또는 opitcal cable)에 의한 광(光)신호로 제어하도록 한 새로운 개념의 전기 제어장치(광 제어장치)에 관한 것으로, PLC와 같은 제어기의 입.출력부에 광파이버를 이용하여 복수개의 광 제어장치 (OFCR)를 연결함으로써 광 제어장치(OFCR)로 제어신호가 전달되게 하고, 광 제어장치(OFCR)의 동작전원은 근처의 상용전원(AC)을 바로 공급받도록 하고, PLC의 동작전원은 파워 스플라이의 전원을 공급받도록 함으로써 광파이버로 간단히 연결는 하면 되므로 종래 처럼 전선에 의한 전기적인 배선이 불필요하여 회로 연결작업이 매우 간단하고 편리하며, 광파이버 (0F)의 유연성을 이용하여 제어신호를 목적하는 장소까지 자유로이 보낼 수 있으며, 또한 광파이버는 전류가 흐르지 않으므로 전기적인 절연이 유지되어 방폭용으로도 사용할 수 있으며, 광파이버(OF)는 PLC와 부하가 멀리 떨어져 있더라도 외부 광이나 전기적인 신호로부터의 간섭이 거의 없으므로 높은 S/N비로 안정된 제어신호를 전달할 수 있어서 부하의 오동작이 방지되고 신뢰성이 향상된다.The present invention provides an optical control device (OFCR) by blocking or integrating an electrical device (actuator or device) and an optical switch connected to an input / output unit of a magnetic field controller (electric or electronic device) such as a PLC. The present invention relates to a new concept of an electric control device (optical control device) that allows an optical signal to be controlled by an optical fiber (optical fiber or opitcal cable) instead of an electrical signal. The control signal is transmitted to the optical control device (OFCR) by connecting a plurality of optical control devices (OFCR) by using, and the operating power of the optical control device (OFCR) is directly supplied with commercial power (AC) nearby. As PLC's operating power is supplied with power splice, it can be simply connected by optical fiber. Therefore, electrical wiring by wire is unnecessary as before. It is convenient and convenient, and it can send the control signal freely to the place by using the flexibility of optical fiber (0F). Also, since the optical fiber does not flow current, electrical insulation is maintained and can be used for explosion proof. Since there is little interference from external light or electrical signal even if the load is far from PLC, it can transmit stable control signal with high S / N ratio, preventing malfunction of load and improving reliability.
