In industrial production process control and monitoring, various instruments are used to form control systems of different sizes. The transmission of various signals between them ranges from millivolts to tens of volts, and even thousands of volts. To effectively solve the problem of signal matching conversion, we usually use signal isolators; During the operation of the system, there are often problems such as signal distortion and mutual interference, which can cause the system to be unstable or even unable to work. In this case, we can also use signal isolators.
A signal isolator is an input-output device that receives an input signal and converts it into an output current or voltage signal to a backend device. It uses optoelectronic or electromagnetic isolation to cut off the electrical connection between the input and output, providing electrical isolation without affecting signal transmission. Selection can be made according to on-site requirements, including signal calculation, signal distribution, signal conversion, etc.
