Optoisolators are used throughout a wide range of industries to provide electrical isolation and ensure signal integrity. The EL815(S)(TD)-V is a photovoltaic output optoisolator that provides reliable, cost-effective and efficient isolation between digital logic signals. This article will discuss the application field and working principle of the EL815(S)(TD)-V.

The EL815(S)(TD)-V is an industrial optoisolator that is suited for a variety of applications. It has a very high common-mode working voltage of up to 10 Vrms and an isolation rating of 4 kVrms. This makes it ideal for use in high-voltage applications such as motor control systems, lighting systems, electrical instrumentation, industrial automation, and automotive electronics. In addition, it comes with built-in overvoltage protection, making it even more suitable for safety-critical applications.

The EL815(S)(TD)-V is an optoisolator with a photovoltaic output. This type of optoisolator is different from the traditional optoisolators in that it does not use a phototransistor as its output device. Instead, it uses a photodiode and a MOSFET as its output circuit. The photodiode detects the optical input signal and generates a photocurrent which is used to turn on the MOSFET. The MOSFET then switches the output signal, providing isolation between the input and the output.

The working principle of the EL815(S)(TD)-V is based on the opto-electronic effect. When an optical signal is incident on the photodiode, it generates an electric current. This current is then amplified by the transistor, which switches the output signal. The isolation between the input and output circuit is based on the high resistance of the photodiode. This ensures that the input signal is kept isolated from the output signal, preventing any crosstalk or interference between the two.

The EL815(S)(TD)-V optoisolator is a reliable and cost-effective solution for applications which require electrical isolation. Its high common-mode working voltage and the built-in overvoltage protection make it suitable for a wide range of industrial applications. In addition, its photovoltaic output circuit provides a reliable isolation between the input and output signals, ensuring signal integrity and preventing crosstalk and interference.
