Optoisolators are electrical components designed to provide galvanic isolation between an input circuit from an output circuit. The output circuit is isolated from any corruption from the input circuit, preventing any noise, static, voltages, temperatures or other unwanted interferences from affecting the operation of the output circuit. Transistor, Photovoltaic Output optoisolators are one type of optoisolators, and the EL815(S1)(TU) is a popular example. This article will discuss the application fields and working principle of the EL815(S1)(TU).

The EL815(S1)(TU) is a high-speed photo-transistor output optoisolator that offers a very high input-to-output isolation of up to 12,500 VRMS. It offers excellent stability over time and temperature changes, and features a very low leakage current. It is primarily used in industrial automation, and motor control applications. It can also be used in switching systems, automotive applications, and in the protection of digital systems from line transients.

The EL815(S1)(TU) operates on a simple working principle. It consists of an LED, a photodiode, and a current amplifier. When the LED is energized, photons are emitted at a certain wavelength and strike the photodiode. This generates a current in the photodiode proportional to the intensity of the light. This current is used to drive the current amplifier, and the output from the current amplifier is the isolated output. This creates a high transmission ratio between the input and the output, and the 12,500 VRMS isolation ensures complete protection for the output device.

The EL815(S1)(TU) optoisolator is a highly reliable and stable device, and is ideal for use in critical applications where isolation is required. It can be used to switch extremely low energy signals with high speed and accuracy. It is also highly resistant to static, electrical, and RF interference due to the high insulation between inputs and outputs. The long expected life and low power consumption makes it an excellent choice for applications where very low power consumption is required.

The EL815(S1)(TU) optoisolator is a highly reliable component and a great choice for a variety of applications. It features a very high level of input-to-output isolation, an excellent stability over time and temperature changes, a very low leakage current, and a very low power consumption. Its simple working principle and highly reliable construction make it an ideal choice for applications requiring isolation and high speed operation.
