Definition: An optocoupler or optoelectronic coupler is an electronic component that basically acts as an interface between the two
An Optocoupler is a combination of LED and a Photo-diode packed in a single package. As we can see in the below-shown circuit diagram, when a high voltage appears across the input side of the Optocoupler, a current start to flow through the LED. Due to this current LED will emit. An optocoupler, also known as an opto-isolator, is an electronic component that transfers electrical signals between two isolated circuits using light.
