This device works on the principle that light is proportional to signal and signal is transferred to a phototransistor. Opto-isolators or Opto-couplers are made up of a light-emitting device, and a light-sensitive device, all wrapped up in one package, but with no electrical connection between the two, just a beam of light. The light emitter is nearly always an LED.
The light-sensitive device may be a photodiode, phototransistor, or more esoteric devices such as thyristors, TRIACs etc.
