In electronics, an opto-isolator, also called an optocoupler, photocoupler, or optical isolator, is a 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 withstand input-to-output voltages up to 10 kVand voltage transients with speeds up to 25 kV/μs.
An elektronesch Apparater, en opto-isolator, och eng optocoupler, photocoupler, oder optesch isolator genannt, ass eng Komponent, datt duerch Hëllef light.Opto-isolators verhënneren héich voltages aus Auswierkungen de System feieren de signal.Commercially sinn tëschent zwee isoléiert Kreesleef elektresch Signaler Transfere opto-isolators bis 25 kV / μs Input-ze-Wasserstoff voltages bis zu 10 kVand Volt transients mat Débit an kënnte Stand halen.
