Optocouplers - Thyristor Signal OutputAn optocoupler, also known as an optoisolator, is an electronic device that uses light to transfer electrical signals between two isolated circuits. An optocoupler with a thyristor signal output is a type of optocoupler that uses a thyristor as the output stage, allowing the optocoupler to control larger loads or higher voltages than other types of optocouplers. Thyristors are solid-state devices that can be used to control the flow of current in a circuit, making them well-suited for use as the output stage of an optocoupler. Optocouplers with thyristor signal outputs are commonly used in applications such as power control and motor control, where the ability to isolate and control high-power circuits is important.
