Photo Triac Coupler use light signals to transmit between circuits to achieve electrical isolation and AC control. They are composed of light-emitting diodes and photoelectric bidirectional thyristors and are ideal for AC load control. Thyristor optocouplers include random phase bidirectional Photo Triac Coupler and zero-crossing bidirectional Photo Triac Coupler .
