Network hub

Network hubs, also known as Ethernet switches or industrial network concentrators, are central devices in industrial automation networks that connect multiple devices such as PLCs, drives, and sensors. These hubs typically feature multiple RJ45 ports, support various data rates (10/100/1000 Mbps), and may include fiber optic interfaces for extended distances. They often provide Power over Ethernet (PoE) capabilities and are designed for DIN rail mounting in control cabinets. Key specifications include port count, switching capacity, and operating temperature range.

These network hubs are deployed in industrial environments including manufacturing plants, process automation systems, building management systems, and energy distribution networks. They facilitate communication in SCADA systems, machine-to-machine (M2M) connectivity, and real-time control loops. Common applications include assembly lines, packaging machinery, material handling systems, and remote monitoring stations where reliable data transmission is critical.

The hubs comply with international standards such as IEEE 802.3 for Ethernet, IEC 61131 for industrial automation, and EN 50155 for railway applications. They are compatible with major automation brands including Siemens, Rockwell AutomationABB, and Phoenix Contact. Many models support industrial protocols like PROFINET, EtherNet/IP, Modbus TCP, and EtherCAT for seamless integration into existing networks.
