Optoisolators – Logic Output is composed of various sizes, shapes and configurations of optocouplers that serve as the building blocks of larger circuits. One of the essential components of the family is the 74OL60103S optoisolator, which is an AC input, DC output optoisolator. The 74OL60103S optoisolator’s potential applications range from the interface of process controllers to digital instruments and their associated analog circuitry. In this article, we will discuss the application fields and working principles of the 74OL60103S optoisolator.

Application Field of 74OL60103S Optoisolator

The 74OL60103S optoisolator is applicable for various purposes. Firstly, it can be used as an AC input, DC output optoisolator in process controllers, particularly in areas with moderate level noise protection requirement. It is also a great choice for digital instruments and their associated analog circuitry. Moreover, it can be used in the combination with an equivalent input transformer for the monitoring of AC load which provides solid isolating effects. Besides, the 74OL60103S makes a powerful choice for being the interface between two systems, such as between an industrial controller and a monitoring display. On the other hand, it can be used as an AC voltage regulator to maintain the voltage at a constant level in medical equipment and other sophisticated equipment.

Working Principle of 74OL60103S Optoisolator

The 74OL60103S optoisolator works by using a LED to transmit a signal inside a molded plastic envelope. Inside the envelope is a photodetector like a photodiode, which turns off the LED and allows power to pass through the device. This type of optoisolator works by two basic principles: electrical isolation and optical coupling. Firstly, electrical isolation is used to prevent interference between the connected devices by blocking the current from the input to the output. Then the optical coupling is the mechanism in which light is used to modulate the output. When the LED is activated, the photodetector receives the light and changes its state from low to high, thus allowing electricity to flow to the optoisolator. The main advantage of this type of opto-couplers is that it offers excellent electrical isolation and good noise immunity at the same time.

Conclusion

The 74OL60103S Optoisolator is a great choice for many application fields, ranging from process controllers to digital instruments and their associated analog circuitry. It is an AC input, DC output optoisolator that works by two basic principles: electrical isolation and optical coupling. Its main advantage is that it offers excellent electrical isolation and good noise immunity, which makes it a popular choice for many applications.
