Optoisolators - Transistor, Photovoltaic Output - Among the variety of optoisolator choices available to engineers today, the FOD819 device is a popular pick. In this article, we’ll discuss the FOD819’s application field(s) and operating principle.The FOD819 is a photosensitive device, meaning that its level or output is affected by the brightness of light that it senses. LEDs are then used to emit a beam of light towards the device, allowing it to receive and determine how strong the input was. This makes it an useful for multiple applications:• Industrial automation• Automobile research & development• Automated train systems• Home security systems• Telecommunications hardware• Medical devicesThese are just a few of the applications for the FOD819, and while it is especially useful when a reliable input is necessary, it may be used for a variety of tasks and purposes.When connected, the FOD819 receives light from an LED and converts it into an electrical current, which is sent to an electronic switch. This switch can then be triggered depending on the level of current that is read. For example, if the FOD819 reads that the current is too low, it will then open the switch and therefore start an automated process. If the current is too high, it will close the switch, and another process will begin. This type of automation makes the FOD819 useful in a wide range of applications.The FOD819 has a few components: a photoreceptor, an amplifier, and a constant current source. The photoreceptor receives the light from the LED, and with the help of an amplifier converts it into an electrical current. This current is then sent to the constant current source, which maintains the current level at a predetermined state. Finally, the output is sent to the switch and triggers the automated process.In summary, the FOD819 optoisolator is a popular choice for many applications, and its ability to convert light into a voltage makes it extremely useful in industrial settings. Its components – the photoreceptor, amplifier, and constant current source – work together to create a reliable output signal, allowing it to be used in a wide range of projects and systems.
