Introduction

The EL817 (S1)(C)(TU)-VG optoisolator is a device that provides isolation between two circuits and utilizes either a photocoupler or transistor output. This device has been designed specifically for high-speed applications, and some of its features include high-isolation voltage, reverse polarity protection, and low-power consumption. In this paper, we explore the application field and working principle of the EL817 (S1)(C)(TU)-VG optoisolator.

Application Field

The EL817 (S1)(C)(TU)-VG optoisolator is suitable for use in a wide variety of applications. It can be used as a sensor in industrial automation, motor speed detection, and automation of general-purpose machines. In home electronic devices, the optoisolator can be used for television set protection, as well as for data transmission in a computer network. It may also be used in energy-saving systems, such as air conditioners, for temperature and humidity control. Additionally, this device can be used for communication between controllers, as well as for the transmission of signals for control between industrial equipment and systems.

Working Principle

The EL817 (S1)(C)(TU)-VG optoisolator works by providing electromagnetic isolation between two circuits. This device consists of an insulated package containing a light-emitting diode (LED) and a phototransistor. The phototransistor is designed to detect the light emitted by the LED and translate it into electrical signals. When light falls on the phototransistor, electrons are freed from its base, and current flows across the collector-emitter junction, which can then be used by the end application. The phototransistor can detect a range of optical intensities, enabling the optoisolator to provide an accurate response over a wide range of light levels.

The main advantage of the EL817 (S1)(C)(TU)-VG optoisolator is that it can provide a reliable solution for applications that require high-speed devices with a high level of isolation between circuits. This device supports a wide range of current transfer ratios (CTR) and operates at temperatures up to 100 degrees Celsius. Additionally, it has been designed to provide high-isolation voltage up to 5 KV RMS. Furthermore, this device has a fast switching speed of 1.4µs, and it can work with low-power consumption of 6 mW.

Conclusion

The EL817 (S1)(C)(TU)-VG optoisolator is a high-speed and high-isolation device that is suitable for use in a variety of applications. It features a wide range of current transfer ratios, a fast switching speed, and low-power consumption. This device can provide reliable isolation between circuits and offers a high level of electromagnetic protection. Furthermore, it has been designed to operate reliably over a wide range of temperatures and isolation voltages.
