Isolators, specifically optoisolators with logic output, are electronic components used to transmit information across an electrical insulation barrier. They are primarily employed for safety or functional reasons, where it is necessary to isolate sensitive components from potentially harmful electrical signals. Optoisolators consist of an input side and an output side that are electrically isolated from each other. The input side typically consists of an LED (Light-Emitting Diode) that emits light when current flows through it. This light is then detected by a photosensitive device on the output side, such as a phototransistor or a photoresistor. Logic output optoisolators are distinguished from other types of optoisolators by the incorporation of additional circuitry on the output side. This includes amplification and threshold detection circuits, which amplify the detected light signal and convert it into logic-level compatible output signals. These output signals can directly interface with common logic signal levels, making them suitable for integration into digital systems. It's important to note that the additional circuitry in logic output optoisolators requires an external power source to operate correctly. This means that an independent power supply needs to be provided to power the amplification and threshold detection circuitry. In summary, logic output optoisolators are isolators that use light to transmit information across an electrical insulation barrier. They incorporate additional circuitry for amplification and threshold detection, allowing them to provide output signals compatible with common logic signal levels. They are commonly used in applications where isolation and protection of sensitive components are necessary.
