Optoisolators are components used in the field of electronics to electrically isolate two or more parts of a circuit. The EL816(X)-V is an optoisolator, specifically a transistor, photovoltaic output, which is best suited for applications such as interfacing sensors or switches with logic circuitry.

The working principle of the EL816 (X)-V is particularly unique because it uses a photo-transistor instead of the usual LED (light emitting diode). A specialized light blocking filter on the photo-transistor keeps it from being affected by other sources of light, which is how most optoisolators function. As opposed to some of the other transistor, photovoltaic outputs that require a voltage across the base and emitter (like a regular transistor), the EL816 (X)-V works on a single DC voltage. This makes it perfect for low voltage applications, such as running on three-volt cell phones.

The EL816 (X)-V has two pins connected to the active chip element, the photo-transistor and the positive terminal of its voltage source. When the photo-transistor is illuminated with a light source, it creates a current which passes through the collector and emitter connections of the optoisolator. This current activates the voltage source and passes it through the output, resulting in an on/off action.

The EL816 (X)-V is well suited for a variety of application fields, such as in a telecommunication system, switching on and off a voltage source for a cell phone, in the audio and video signal processing industry, and for fiber optics communications. Its unique attributes - such as a photovoltaic output and its single DC power supply - make it ideal for low voltage applications, ensuring reliable and secure data transmission with minimal power consumption.

Overall, the EL816 (X)-V is a pivotal optoisolator that caters to a variety of application fields, while being particularly useful in the audio and video signal processing industry and data transmission applications. Its unique advantage of having a single DC voltage source and photo-transistor make it an attractive choice for low voltage applications, where reliability and power efficiency are vital.
