A photocoupler, or optical isolator or an opto - isolator is a component that transfers electrical signals between two isolated circuits by using light. Opto - isolators prevent high voltages from affecting the system receiving the signal. . Opto - isolators are usually used for transmission of digital (on / off) signals, but some techniques allow use with analog (proportional) signals.

The EL817 Phototransistor Photocoupler consists of infrared emitting diodes, optically coupled to a phototransistor detector. They are packaged in a 4-pin DIP package.
