How A Photocoupler Works?
Photocouplers consist of an infrared LED (emitting device) and a photosensitive receiving device optically coupled into the same package. What this does is allows electrical signals to be passed from the input to the output circuit; separated by an isolation barrier that is designed to withstand high voltage levels. This find it’s way in many applications for safety reasons, as well as to prevent the damaging of expensive or important electrical components.

Product Applications
Photocouplers are used in solar power applications to isolate user-accessible circuitry and components from the high-voltage provided to the grid.
Programmable Logic Controllers (PLC) use photocouplers to isolate important low-voltage logic circuitry from high voltage transients and higher voltage circuits.
In charging equipment and devices, photocouplers act as a feedback to ensure that the output circuit never exceeds a preset voltage level.
Light dimmers use photocoupler tech to ensure user safety, and also to isolate high and low voltage circuitries in a reliable manner.
