Optoisolators with Triac or SCR (Silicon Controlled Rectifier) output are devices designed to provide electrical isolation between input and output circuits while allowing control of AC power loads. They consist of an LED optically coupled to a thyristor-based output stage, enabling them to switch high-voltage AC loads such as motors, heaters, and lamps in applications like motor drives, solid-state relays, and lighting controls.
