OEP14 Resistive Optocouplers 
Resistive optocouplers are early optical isolation devices. They come in various options. Let me describe OEP14 model.
This model uses a photo resistive cell as a photo electric detector and the filament bulb as an emitter.
Widely-spread photo resistive cells generally employ cadmium selenide and cadmium sulphide as semiconductors. Light falling on such resistive ...
