Industrial grade protection capability

The aluminum wavy shell enhances vibration resistance, and the wide voltage input and temperature range ensure stable operation in extreme environments.

Modular scalability

It can be directly integrated into the master or slave station, expanding the system bus topology and simplifying complex network deployment.

application area

Power industry: Used for redundant communication support in substation automation and generator control systems.

Elevators and Machinery: Enhance the fault tolerance of the elevator control system bus to ensure safe operation in emergency situations.

Automotive manufacturing: supports high-speed data exchange and fault self recovery of production line equipment such as robots and conveyor belts.

Metallurgy and Chemical Industry: Ensuring the stability of data transmission between PLC and sensors in high temperature and dusty environments.
