Optoisolators are solid state devices that provide electrical isolation and protect sensitive electronic equipment from damaging power spikes, surges, and transients. The EL217 optoisolator uses a transistor photovoltaic output and can be used to switch and control high current applications up to 2A, making them ideal for applications requiring high-current signal isolation.

The EL217 optoisolator is designed to provide protection between two connected devices, keeping the electrical signals or power from one device isolated from the signals of the other device. The main components of the optoisolator are a photocell that detects and converts optical signals into electrical signals, a light source to emit light, and a transistor to amplify the electrical signal from the photocell.

The photocell is the most important component of the optoisolator and is responsible for converting the optical signal transmitted from the light source into an electrical signal. The light source is usually a LED (light-emitting diode) that emits a specific type of light, usually infrared or visible light. The LED emits light which activates the photocell, the photocell then converts the light into an electrical current, which is then amplified by the transistor.

The amplified electrical signal is then directed to a load which is an electrical component that is either powered by the signal or controls it. This signal can be used to command or control devices such as motors, relays, lights, etc. It is also used to switch on or off an electrical device. In some applications, the signal can even be used to power an electrical device.

The EL217 optoisolator also comes with a wide selection of features which can be used to protect the optoisolator from power transients, surges, and other electrical spikes. These features include high voltage protection, low input and output impedance, thermal protection, and short circuit protection.

The EL217 transistor photovoltaic output optoisolator is a versatile and reliable device that can be used to switch and control high current applications up to 2A. It is well-suited for applications that require electrical isolation, noise immunity, and protection from electrical spikes and surges. Its wide selection of features makes it an ideal choice for any application that requires signal isolation and high-current switching and control.
