Key Features:
Powerful Expandability:
Supports up to 32 I/O modules, allowing users to flexibly combine different types of modules based on project requirements. This flexibility makes it suitable for both small-scale automation lines and large, complex industrial control systems.Wide Application Scenarios:
Due to its wide variety of modules and strong expandability, the RB Series can be widely applied in various industries:
Intelligent Warehousing & Logistics: Control of equipment operations in logistics and warehouse automation.
Building Automation: Environmental parameter regulation in smart building systems.
Energy Industry: Equipment monitoring and control in energy management systems.
Manufacturing Automation: Automation control for production lines in the manufacturing sector.


- Space - Saving
The module thickness is as thin as 12mm, similar to the thickness of a piece of paper.
It can save 2/3 of the electrical cabinet space. Compared with other modules' electrical cabinets, the RB module electrical cabinet takes up much less space, which is very suitable for scenarios where space is limited. - Easy Debugging
Our company provides the upper - computer software IOTesterTool for customers to debug the modules.
The software supports functions such as parameter modification, point - setting, and module diagnosis, making the debugging process more convenient and efficient.
