As a result, optical couplers or photocoupler s can be found in an unexpectedly large number of circuits. They are even used in solid-state relays, where an optical coupling is used to electrically isolate the input and output while allowing the output to be switched based on the input state. Photocouplers or optocouplers serve many functions: they can be used to link data across two circuits, they can be used within optical encoders, where the optocoupler detects visible edge transitions on an encoder wheel to detect position, and they can be used in a variety of other circuits where optical links and transitions are required. Photocouplers or optocouplers are typically contained in a single package, which is often about the size of an integrated circuit, though this varies greatly depending on the intended application. is a semiconductor device that couples a signal from one electrical circuit to another while providing electrical isolation. Īn optocoupler, also known as a photocoupler. Optocouplers are known by a variety of names, including optoisolator and photocoupler.
