Industry 4.0, also known as intelligent industry + Internet, is a new stage of modern industrial information development. Some devices such as robots, UAVs, equipment monitoring, computers, industrial switches and data * are seamlessly combined through artificial intelligence, and industrial switches play the role of information transmission in the infrastructure of industrial Ethernet. Facing the harsh industrial environment, we must have seven unique skills. Our industrial Ethernet switch series is a two-layer management Industrial Ethernet switch that meets the requirements of industrial design. It adopts mature technology and open network standards. It is suitable for low temperature and high temperature, strong anti electromagnetic interference, salt fog prevention, earthquake resistance and anti shaking. It is equipped with redundant dual DC power supply (24V / 48V), which meets the requirements of the harsh working environment on the industrial site and provides an efficient, reliable and fast solution for the industrial Internet of things. Industrial switching * in the network convergence layer, you can choose from a variety of electrical and optical port configurations. It can be used in various field environments and can be flexibly networked. It can be widely used in industrial control automation, road traffic control automation, building automatic control system, mine automatic control system, oilfield control automation, hydropower station control automation, power system control automation, machine room monitoring system, intelligent logistics and other industrial application scenarios. It can work stably, reliably and efficiently to create a rock stable industrial Internet of things.
