Optoisolators - Transistor, Photovoltaic Output

Optoisolators are one of the most common types of optocouplers. An optoisolator is essentially a device that uses light to provide electrical isolation between two circuits, typically a high-voltage AC input circuit and a lower-voltage driven circuit. One of the most commonly used types of optoisolator is the 4N26FR2VM optoisolator, which combines a reducing photo transistor with a photovoltaic output.

Application Field of 4n26FR2VM

The 4N26FR2VM optoisolator can be used in a number of application areas including automotive, audio-visual, medical, industrial, telecom, consumer and military. It is a reliable and efficient device which can be used in a wide range of applications, including level detection, dark-light sensing, motor speed control, relay control and many other functions. The 4N26FR2VM has a response time of 0.15 milliseconds, meaning it responds quickly and reliably in a variety of situations.

Working Principle of 4N26FR2VM

The 4N26FR2VM works by using a photovoltaic cell to detect the presence of light. The light then triggers the photovoltaic cell to produce a small electrical current which is then used to power the phototransistor. The phototransistor then produces a low voltage (typically around 5v) voltage which can be used to control or switch the external circuit. The 4N26FR2VM is particularly useful in applications where there is a need for electrical isolation between the input and output circuits, as the optoisolator provides a high degree of electrical noise immunity.

The 4N26FR2VM is particularly well suited to applications where relatively high current loads are needed, as the phototransistor can be used to switch higher currents than other optoisolators. Additionally, the 4N26FR2VM is able to operate at higher temperatures than other optocouplers, meaning it can be used in a wider range of applications. Overall, the 4N26FR2VM is a reliable and robust optoisolator which is capable of providing electrical isolation in a variety of circumstances.
