1. Introduction to Optocouplers
Optocouplers, also known as optoisolators or photocouplers, are electronic devices that provide electrical isolation between input and output circuits. They consist of a light-emitting diode (LED) and a photodetector, typically a phototransistor or photoresistor. When an electrical signal is applied to the input side, the LED emits light, which is then detected by the photodetector, resulting in an output signal.
