WebSep 1, 2024 · Opto-isolators act as a protection mechanism, ensuring that harmful electrical currents cannot flow across the device. In simplest terms, an optoisolator works by taking an input electrical signal and converting it into a light signal using a light-emitting diode, generally operating in the near-infrared spectrum.
WebThe opto will provide isolation of 1500V or more depending on the device selected. A number of companies make optoisolators. A common family is the 4N3x series. Figure 11-1 shows an opto driving an input. This section will use the 4N32 as an example.
