WebMay 7, 2024 · Optocoupler. Opto-coupler is an electronic component that transfers electrical signals between two isolated circuits. Optocoupler also called Opto-isolator, photo coupler or optical isolator. Often in circuits, especially low voltage or highly noise sensitive circuits, Optocoupler is used to isolate circuitry to prevent electrical collision ... The earliest opto-isolators, originally marketed as light cells, emerged in the 1960s. They employed miniature incandescent light bulbs as sources of light, and cadmium sulfide (CdS) or cadmium selenide (CdSe) photoresistors (also called light-dependent resistors, LDRs) as receivers. In applications where control linearity was not important, or where available current was too low for … flamethrowers description
