Solid state relays (SSRs) are usually composed of an LED, a detector, and a thyristor, so they are also called LED relays or opto-couplers. They are used in various fields, such as well-developed industrial automatic control, computerized control and household electrical appliances, to transfer electrical signals, and have the characteristics of "closed loop" and "infiltration".

The working principle of SSR is mainly based on the light coupling effect, that is, the LED emits light, which is converted into electric signal by the receiving element, and then transmitted to other devices to control the switch or drive state. The LED and the detector are completely sealed in the same envelope. The LED emits light to the detector through the window, and the detector senses the light and produces a corresponding output signal. When power is applied to the LED, the current flowing through the LED will cause it to emit light, and the light incident on the detector will generate a certain potential on the output of the detector. This potential is used as the control signal of the thyristor and realizes the zero-crossing switching of the thyristor.
