Photo Triacs
Via a transparent isolating material a photo triac, also called opto triac, of the manufacturer Cosmo, Everlight and CT Micro optically links an infrared LED and a phototriac within one housing. Photo Triacs are typically used as solid-state AC switches.
Quite generally there are two classes of phototriacs available: with and without zero-crossing circuit. This internal circuit makes the triac switch on or off only when the applied alternating voltage is near the zero-value. A Photo Power TRIAC is a photoelectric isolation switch device, which can used a small signals to control the internal high current bidirectional thyristor (Power TRIAC) turn on and turn off. The input and the output is isolated by photoelectric. When the input is DC or pulse signals, the output terminal can be transit from off state to conductive. Directly driving a high current load with a small control signal.
