Working Principles

The EL8176FWZ-T7A optocoupler consists of an infrared LED and a phototransistor. When a forward current is applied to the LED, it emits infrared light. This light is then detected by the phototransistor, causing it to conduct current between the collector and emitter terminals. The optocoupler provides electrical isolation between the input and output circuits, allowing signals to be transferred without direct electrical connection.
