PC817 Optocoupler Module Features An Optocoupler, is an electronic component that interconnects two separate electrical circuits by means of a light sensitive optical interface.There is a is a light emitting diode with a phototransistor inside the optocouplers, both of them are isolated from the external environment of the optocoupler; This means that the internal phototransistor can only receive light emitted by the internal light emitting diode. The phototransistor base is stimulated by light receive...
