WebFeb 10, 2024 · Okay, now we know that a common analog optocoupler also called an analog optical isolator (AOI), consists of a light-tight package which houses a light source and one photoconductive cell. Through control of the input current (or voltage) applied to it, the output resistance can be varied. An opto-isolator (also called an optocoupler, photocoupler, or optical isolator) is an electronic component that transfers electrical signals between two isolated circuits by using light. Opto-isolators prevent high voltages from affecting the system receiving the signal. Commercially available opto-isolators … See more The value of optically coupling a solid state light emitter to a semiconductor detector for the purpose of electrical isolation was recognized in 1963 by Akmenkalns, et al.
