Introduction

The EL815(S)(TB)-V is an optoisolator, specifically one with a transistor, photovoltaic output, which is used for electrical isolation, protecting both the user and connected peripheral systems against external voltage or electro-magnetic disturbance. This type of optoisolator is also capable of detecting a wide range of electrical signals, from very low level current to high voltage pulses, and is capable of multiplexing, making it highly reliable and ideal for use in a range of applications.

Application Field

The EL815(S)(TB)-V is well suited for use in a variety of electrical isolations needs in consumer electronic products, because of its high reliability and versatility. It is used as an isolation barrier between microprocessors and their peripheral systems, protective circuits for motor control systems, and for providing feedback control signals for power supplies and services such as dimmers and amplifiers. Also, these optoisolators are found in audio systems, communications systems, vehicle control systems, and automotive applications.

Working Principle

This optoisolator operates by detecting the electrical signal from one side and converting it into a light source in the form of an LED in order to isolate the source from any external voltage. The light source then passes through an insulation layer before striking a photodetector, producing an electrical signal from the other side. The electrical signal can then be used to drive circuits, control motors, or provide feedback signals as necessary.The light emitting diodes (LEDs) of the EL815(S)(TB)-V are designed to be extremely efficient in terms of both voltage and current usage. This efficiency means that these devices are able to detect low level signals and low voltage pulses, while still providing the necessary electrical isolation required for a wide range of applications.

Conclusion

The EL815(S)(TB)-V optoisolator helps to provide electrical isolation for a wide range of products, from microprocessors to automotive systems. This makes it an ideal choice for many consumer electronic applications. Additionally, the wide range of electrical sensitivity allows for multiplexing while providing reliable isolation from external voltages and disturbances. As a result, this optoisolator is a reliable and versatile choice for many applications.
