The photocoupler is a semiconductor photoelectric device which has been developed in recent years. Due to its little size, long lifespan, good anti-jamming function, wide working temperature range and total separation of input and output without touch, etc, it is widely used in electronic technology area and industrial automation control, besides, it can replace relays, transformers and wave chopper, so it could be used in separation circuits, switch circuit, D/A shift, logic circuit, overcurrent protection, long line transmission and LEV distribution, etc.
