Working Principles

The PS8551L4-V-E3-AX is an optocoupler that utilizes an infrared emitting diode to emit light when forward biased. This emitted light is then detected by the phototransistor, which generates a corresponding electrical signal. The electrical signal is then transferred between the input and output circuits, providing electrical isolation.
