WebAn optocoupler provides signal transfer between an isolated input and output using an infrared Light Emitting Diode (LED) and a silicon phototransistor (Figure1). The LED sends a beam of infrared energy to an optical receiver inside a single package with a light conducting medium between the emitter and the detector. This mechanism provides フォトカプラ(Photocoupler. Opto-isolator, optocoupler, optical isolator とも呼ばれる)は、内部で電気信号を光に変換し再び電気信号へ戻すことによって、電気的に絶縁しながら信号を伝達する素子である。フォトカプラが直接スイッチングできる電流は小さく、大きな電流をスイッチングできるパワー半導体（トライアック、サイリスタ、IGBT）などの前段でトリガーとして使用される。 WebIt has both a non-isolated output and an opto-isolated output.
