Working Principles

The EL8170IS optocoupler consists of an infrared LED and a phototransistor. When a current is applied to the LED, it emits infrared light. This light is then detected by the phototransistor, causing it to conduct current. The optocoupler provides electrical isolation between the input and output circuits while allowing signal transmission through light.
