Optocoupler working principle
This diagram explains the working of an optocoupler (opto-isolator). It contains an internal LED on the input side and a light-sensitive transistor on the output side, separated by an insulating barrier. When an input voltage is applied, current flows through the LED, causing it to emit light. This light activates the phototransistor, allowing ...
