Optoisolators, also known as optical isolators or optical couplers, are devices that use optical components to isolate two parts of a system while allowing them to interact. The IS355 is a type of optoisolator with a transistor and photovoltaic output. In this article, we will look at the application fields and working principle of the IS355 optoisolator.

Application Fields

The IS355 has a wide range of applications, particularly in control systems, automotive applications, and communications systems. In a control system, the IS355 can be used to control a motor or other motor-based device. In an automotive application, the optoisolator can be used to sense voltage, temperature and other parameters in a car’s electrical system. In a communications system, it can be used to help detect errors in data transmission and enable data transfer without interference from outside sources.

The optoisolator is also useful in the field of medical electronics, such as in MRI scanners, where it can be used to help detect and diagnose ailments. The optoisolator is also useful in industrial automation, as it can help control various types of machinery and can be used to regulate safety barriers. In short, the IS355 has application fields in a wide variety of industries.

Working Principle

The IS355 optoisolator is made up of two main parts: a phototransistor and a photovoltaic cell. The phototransistor converts an electrical signal into an optical signal, while the photovoltaic cell converts the optical signal back into an electrical signal. This allows the two parts to interact with each other without any electrical interference. The optoisolator is used to monitor, control, and protect electrical systems.

The IS355 optoisolator has two input terminals, VIN and GND, and two output terminals, OUT and GND. When a voltage is applied to the VIN terminal, the phototransistor will create an optical signal. This signal will be received by the photovoltaic cell, which will convert it back into an electrical signal and output it at the OUT terminal. This process is known as photoelectric conversion and is used to help transfer information without interference from outside sources.

The IS355 optoisolator also has a motor control feature. This feature is used to help control and monitor DC motors. The phototransistor and photovoltaic cell in the optoisolator can detect the current in the motor, allowing for precise control over the speed of the motor. This type of precise control is useful for applications such as robotics and automation.

Conclusion

The IS355 is an optoisolator with a transistor and photovoltaic output. It has application fields in a wide variety of industries, from automotive to medical electronics. The optoisolator has two input terminals, VIN and GND, and two output terminals, OUT and GND. It also has a motor control feature that helps to control and monitor motors. In short, the IS355 is an optoisolator with a wide range of applications and features, making it a versatile and useful optoisolator.
