Working Principles

The EL8173ISZ-T7 optocoupler consists of an infrared LED and a phototransistor. When current flows through the LED, it emits infrared light that is detected by the phototransistor. The phototransistor then amplifies the received signal and outputs it to the collector-emitter circuit. This allows for electrical isolation between the input and output circuits while transmitting the desired signal.
