Description:
An optocoupler is a part that transmits an electrical signal between two isolated circuits, which is performed by light. Optocouplers prevent the damage that high voltages may cause to the signal receiving system. Common optocouplers consist of an LED and a phototransistor in one package. IC EL6N137 is a single optocoupler with a phototransistor type output with base transistor connection.
