HSR Industrial Ethernet Switch NEU20102FGP – 8FE + 2x 1G SFP Unmanaged

NEU20102FGP is an unmanaged HSR industrial Ethernet switch designed for resilient, low‑maintenance networking in harsh environments. It provides 8 Fast Ethernet RJ45 ports for field devices and 2 Gigabit SFP uplink ports for scalable fiber connectivity between control cabinets, lines and remote enclosures. One‑click HSR seamless redundancy ring and one‑click VLAN isolation reduce engineering time by enabling high‑availability rings and basic traffic segmentation without complex configuration. Key features include one‑click broadcast storm suppression, fanless aluminum housing, ‑40 to 75 °C operating temperature, redundant 12–52 V DC power inputs with reverse‑polarity and surge protection, and industrial EMC immunity with CE, FCC and RoHS compliance.

HSR Ring Topology and Typical Applications
High‑availability Seamless Redundancy (HSR) is an industrial Ethernet redundancy protocol that provides seamless failover by sending duplicate frames around a ring in both directions, so communication continues without interruption even if a single link fails. NEU20102FGP uses its two Gigabit SFP uplinks to form an HSR ring between multiple cabinets or panels, while the 8 Fast Ethernet ports connect local PLCs, HMIs, drives and I/O at each node. Typical applications include control cabinets, robotic cells, packaging lines, process skids and distributed monitoring systems in power utilities, factory automation, transportation and infrastructure projects where zero‑recovery‑time redundancy and wide‑temperature operation are required.

Integration with Industrial Ethernet Protocols
NEU20102FGP is protocol‑transparent at Layer 2, so it can carry most Industrial Ethernet protocols, including Modbus TCP, EtherNet/IP, PROFINET RT and EtherCAT, without special configuration. Deterministic fieldbus traffic and standard TCP/IP services can share the same HSR ring, while VLAN isolation helps separate production cells, maintenance networks and camera streams on a single physical infrastructure. By combining HSR seamless redundancy, robust industrial hardware design and broad protocol compatibility, NEU20102FGP provides a simple “plug‑and‑run” HSR switch solution for OEM machine builders, system integrators and end users who need to increase network availability without deploying complex managed switching platforms.
