alsThe ORPC-817M/B Optocoupler with Through Hole RoHS manufactured by Orientals is a solid-state device which enables electrical isolation between input and output circuits. The device consists of an infrared LED which is optically coupled with a phototransistor, an integrated high-impedance output stage, and a robust package enclosed in a 6-pin through hole package. Its isolation voltage is 4.17kVrms. It can be used to convert digital signals, analog signals, control signals, or power signals from one circuit to another without any direct electrical connection.
