Opto-isolators provide electrical isolation between circuits in I/O modules by using light to transmit signals, preventing ground loops and protecting sensitive components from voltage spikes.
Relays use electromagnetic coils to mechanically switch contacts, handling higher power loads, while opto-isolators use semiconductor-based light transmission for signal isolation with faster switching speeds.
Our components feature semiconductor materials for opto-isolators, copper wire coils, polymer housings for insulation, and ferromagnetic cores in relays to ensure reliability in demanding manufacturing environments.
