WebSep 29, 2024 · Working Principle of Photocoupler. The photocoupler's principle is to supply an electrical signal to the photocoupler's input to cause the light-emitting source to emit light. The magnitude of the excitation current determines the light intensity. The photoelectric effect generates a photocurrent once this light is irradiated on the packed ... WebAn optocoupler (also called optoisolator) is a semiconductor device that allows an electrical signal to be transmitted between two isolated circuits. Two parts are used in an optocoupler: an LED that emits infrared light and a photosensitive device that detects light from the LED. Both parts are contained within a black box with pins for ...
