Working Principles

The EL8178AIW-T7 is an optocoupler that utilizes a phototransistor to transfer electrical signals between two circuits. When a current flows through the input LED (Anode and Cathode), it emits light that activates the phototransistor. The activated phototransistor allows current to flow between the Collector and Emitter, effectively transferring the input signal to the output circuit while providing electrical isolation.
