1、 The function and working principle of linear resistor isolator:

The main function of a linear resistance isolator is to measure resistance signals accurately at high speed and convert them into standard analog signal outputs through isolation. The working principle of linear resistance isolators is based on the basic principles of electrical isolation and signal conversion. It is usually composed of components such as transformers and optocouplers, which cut off the electrical connection between the input and output terminals through physical isolation. When a signal or power reaches the isolator from the input end, the internal components of the isolator will convert it into another electrical signal, and then output it to the outside again through physical isolation. This conversion and isolation process can prevent the propagation of interference and noise, improving the safety, reliability, and stability of the circuit system.

2、 Application of LYD series linear resistor isolator:

It can not only be directly connected to pointer meters and digital displays, but also to automatic control instruments (such as PLC), various A/D converters, and computer systems. It is widely used in automation systems in industries such as power, railway, petrochemical, metallurgy, chemical, food, and warehousing. Linear resistor isolator is a cost-effective product that can improve the anti-interference ability of industrial production processes, ensure system stability and reliability.
