Managed Industrial DIN-Rail 8-Port Gigabit Ethernet + 4-Port Gigabit SFP Network Switch

This product series features an industrial DIN-rail design. The 8-Port Electrical + 4-Port Optical Managed Gigabit Redundant Ethernet Switch represents a new generation of multi-service access switches, characterized by high integration, rich functionality, and ease of use—setting the highest standard within the industry.

Equipped with 8 Gigabit electrical ports and 4 Gigabit optical ports, it is particularly well-suited for scenarios involving high data throughput, such as video transmission. The switch supports a comprehensive suite of Layer 2 management protocols essential for diverse industrial networking applications. Furthermore, it supports the ITU G.8032 redundant ring protocol, enabling the configuration of various network topologies—including cascaded, single-ring, and tangent-ring structures—with a self-healing time of less than 20ms, thereby ensuring the real-time performance and stability of the network. Built upon mature technologies and open networking standards, this switch is designed to withstand extreme temperatures, resist strong electromagnetic interference, and offer protection against salt mist, vibration, and shock. It meets the rigorous operational demands of harsh industrial environments, providing an efficient, reliable, and rapid networking solution for the Industrial Internet of Things (IIoT).
