4、 Introduction to Common Module Functions

Yudian adopts a modular approach that allows customers to install their own instruments to form the input/output of the instruments. By installing different modules, the functions of the instruments can be flexibly configured to "customize" their ideal instruments. At the same time, the manufacturer also achieves mass production, fast delivery, and zero product inventory, providing customers with products with higher performance/price ratios. There are dozens of modules available for customers to choose from, including various analog and switch input and output modules, communication and power modules, etc.
