The EL817 optocoupler consists of an infrared emitting diode optically coupled to a phototransistor.  It comes in a 4-pin DIP package but also available in SMD variant. It can be used for electrically isolated communication in programmable controllers, copiers, registers, and signal transmission between circuits with different working voltages.
