Optoisolators, or optocouplers, are electronic devices that use a light-emitting diode (LED) to isolate one circuit from another. The EL817-G is a particular type of optoisolator that uses a transistor, photovoltaic output to connect two circuits. This article will discuss the application field and working principle of the EL817-G optoisolator.

The EL817-G optoisolator is designed to provide superior insulation between two circuits, while also providing a low-to-medium current connection. It features a high dielectric strength between the input and output of up to 8,000V, and its isolation is rated at 2,000Vrms. This makes it ideal for use in safety-critical applications, such as industrial power devices, telecommunications, and medical equipment.

The EL817-G optoisolator consists of a LED, a phototransistor, and an interface circuit. When the LED is energized by an input signal, it emits light, which is detected by the phototransistor. The phototransistor then switches on a power transistor, which passes the input signal to the output. This creates an isolated connection between the two circuits.

The EL817-G optoisolator can be used in a variety of applications. One example is medical equipment, where a non-isolated signal could cause an electric shock to the patient. The EL817-G optoisolator ensures that electrical shock is avoided. Another application for the EL817-G optoisolator is in industrial automation systems, where it is used to isolate and control equipment. It can also be used to control and monitor the operation of motors and other motors related equipment.

The EL817-G optoisolator can also be used to provide protection against electrical surges and transient signals. It can detect and isolate any vulnerable signals from entering a system, thus protecting delicate circuits from harm. This ensures that the system continues to operate properly without any damage.

In addition to its insulation and protection capabilities, the EL817-G optoisolator is also designed to provide good linearity. This means that the output of the optoisolator is proportional to the input signal. This ensures that the output signal stays within its specified range, and that no distortion occurs.

The EL817-G optoisolator is a useful and versatile type of optoisolator. It provides superior insulation and isolation for critical applications, as well as good linearity and surge protection. It can be used in a variety of applications, including those in the medical and industrial automation industries. With its durable construction and high-performance features, the EL817-G optoisolator is an excellent choice for any circuit isolation needs.
