EL817 (S)(TU) Application Field and Working Principle

Optoisolators – Transistor, Photovoltaic Output are devices which allow the transfer of signals from one circuit to another without a direct electrical connection. This reduces the risk of components damaged by voltage spikes, EMI, or noise. The EL817 (S)(TU), also known as 4N25 and TLP2288, is one such optoisolator that is widely used for these applications.The EL817 (S)(TU) consists of a gallium-arsenide infrared LED (light-emitting diode) and a matching phototransistor. Light from the LED is detected by the phototransistor, and the resulting electrical signal is used to switch a low-voltage, low-power circuit. This makes the device ideally suited for use in low-voltage digital circuits, such as microcontrollers, I/O converters, PLCs, solenoids, analog-to-digital converters, and many other applications.One of the primary advantages of the EL817 (S)(TU) is its low power consumption. The LED consumes only 10 mA at a voltage of 5V, and the phototransistor requires no power at all when in use. This makes it very energy efficient and ideal for applications where low power consumption is a crucial factor. The EL817 (S)(TU) is also highly reliable and has a very long lifetime.The EL817 (S)(TU) works by emitting a light signal when a voltage is applied to the LED. This light is detected by the phototransistor, which converts the light signal into an electrical signal. This electrical signal is then used to switch a low-voltage, low-power circuit. The device is typically used in applications that require low-power operation. It is also used as an interface between circuits that operate at different levels of voltage and current.The EL817 (S)(TU) can be used in a variety of applications. It can be used as an optocoupler to isolate an input signal or to switch a circuit on and off. It can also be used to provide feedback for control systems. The device is typically used in low noise, high speed, low power applications, such as servo controllers, limit switches, and testers.The EL817 (S)(TU) is a highly reliable and versatile optoisolator. It is an ideal choice for low-voltage digital circuits, providing reliable and energy-efficient performance. It is also highly reliable and has a long lifetime, making it an excellent choice for a variety of applications.
