Source: InternetPublisher:李商隐身 Keywords: AC contactor interface circuit triac BSP Updated: 2021/12/28
The device is used as an intermediate relay. As shown in the figure is an AC contactor interface circuit using a bidirectional thyristor .
Among them, MOC3041 is an optocoupler that uses a bidirectional thyristor output and is used to trigger the bidirectional thyristor KS. When Pl0 is low, KS will
conduct, energizing the AC contactor coil.
