FODB100

Optoisolators – Transistor, Photovoltaic Output, or FODB100, are an important type of electrical isolation device and play an important role in protecting circuitry from electric shock. They are widely used in many applications, ranging from power supply isolation, to low-voltage motor controllers, to industrial automation systems.

The FODB100 utilizes a combination of a light source (typically a light-emitting diode), a photo detector (typically a photovoltaic device), and a power electronic device (typically a transistor) to create a series of electrical signals. This series of electrical signals constitute an optical interface between two electrically isolated systems.

The basic working principle of FODB100 is based on the phenomenon of light-generated electric current. When light is incident onto a photovoltaic cell, it creates a dc voltage across it. This voltage is then connected and isolated from the other electrical input circuits by means of two transistors, with only a few connections between them.

The first transistor acts as a \'switch\' – allowing the photovoltaic cell\'s voltage to go through or be blocked out. When the voltage is on, it turns the transistor on, which in turn triggers the second transistor to switch on. This switching of the second transistor then sends an output signal to the electrical circuit connected to it, such as a motor controller or light dimmer.

The FODB100 also has a number of protection features. It has a wide operating spectrum, as well as 4000 Vac-rated isolation against external fields. The device also has a current rating of up to 2A, and its operating temperature range extends from -40 to +85°C. As such, it is a very reliable optoisolator device, making it an ideal choice for a wide range of industrial automation applications.

Optoisolators – Transistor, Photovoltaic Output, or FODB100 – are a vital component for many applications in electronics and electrical engineering. This device is rugged, reliable, and offers an effective way to protect circuits from electric shock. The wide operating spectrum and effectiveness in protecting external fields make it a preferred choice for industry professionals and engineers.
