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. (US patent 3,417,249). Photoresistor-based … 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 Resistive opto-isolators The earliest opto-isolators, originally marketed as light cells, emerged in the 1960s. They employed miniature incandescent light bulbs See more • Galvanic isolation 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. Some optocouplers have a slotted coupler/interrupter … See more • S.
