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. See more 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 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. (US patent 3,417,249). Photoresistor-based opto-isolators were introduced in 1968. … See more Resistive opto-isolators The earliest opto-isolators, originally marketed as light cells, emerged in the 1960s. They … See more • Galvanic isolation See more An opto-isolator contains a source (emitter) of light, almost always a near infrared light-emitting diode (LED), that converts electrical … See more Electronic equipment and signal and power transmission lines can be subjected to voltage surges induced by lightning, electrostatic discharge See more Usually, optocouplers have a closed pair configuration. This configuration refers to optocouplers enclosed in a dark container wherein the source and sensor are facing each other. See more
