Introduction
An optoisolator is a component used to provide electrical and optical isolation between two parts of a circuit. A particular type of optoisolator that uses a transistor as a photocoupler is known as the IL252-X017T optoisolator. It is a four-pin component with a single-channel photovoltaic output. This article will discuss the application field and working principle of this optoisolator.Application Field
The IL252-X017T optoisolator is used in many electronic circuits including motor controls, high-voltage and safety circuits, and electrical security applications. Often, it is utilized in power switching circuits, with a low voltage DC control used to switch high-voltage AC power for applications including switching on or off a heater or other DC equipment. Additionally, the optoisolator is used in computer peripherals, such as modems, if the signal to be transmitted is routed through a high voltage power line and must be isolated from the microprocessor.Working Principle
The basic operation of the IL252-X017T optoisolator is as follows: A light-emitting diode (LED) generates a beam of light that is then received by the photovoltaic output component, usually a photosensitive transistor. This transistor receives the beam of light and is triggered to produce a voltage drop between its base and emitter, thus switching on the transistor. The collector voltage is used to drive the output devices, and the output signal output is derivedfrom the collector voltage.In the case of the IL252-X017T optoisolator, an LED is used to generate a beam of light which then passes through a specially designed lens and is directed into the photosensitive transistor. The transistor then produces a voltage drop between its base and emitter, thereby switching on the transistor. This electric current then passes through an output resistor, and the output signal is determined by this output resistor.Conclusion
