Opto-isolated inputとは

WebAn optocoupler provides signal transfer between an isolated input and output using an infrared Light Emitting Diode (LED) and a silicon phototransistor (Figure1). The LED sends a beam of infrared energy to an optical receiver inside a single package with a light conducting medium between the emitter and the detector. This mechanism provides 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.
