WebDec 10, 2024 · An opto-isolator connects input and output sides with a beam of light modulated by input current. It transforms useful input signal into light, sends it across the dielectric channel, captures light on the output side and transforms it back into electric signal. Unlike transformers, which can pass energy in both directions with low losses, … Weboptoisolator (optical coupler or optocoupler): An optoisolator (also known as optical coupler , optocoupler and opto-isolator ) is a semiconductor device that uses a short optical transmission path to transfer an electrical signal between circuits or elements of a circuit, while keeping them electrically isolated from each other. These ...
