Moxa EDS-208A Series – 8-Port Industrial Ethernet Switches for Harsh Environments

The EDS-208A Series by Moxa offers compact, unmanaged Ethernet switches with up to 8 ports, built for demanding industrial conditions. Depending on the model, users can choose from up to 8 copper (RJ45) ports and up to 2 fiber optic ports (SC/ST connectors, multi-mode or single-mode).

With redundant power inputs supporting a wide voltage range (9.6–60 VDC), the series is ideal for hazardous locations, transport systems, and maritime applications, fully certified by global standards. The -T models withstand -40 to 75 °C, making them perfect for outdoor cabinets or environments with extreme temperature fluctuations.

A built-in broadcast storm protection feature, enabled via DIP switch, enhances network resilience. Each unit undergoes a 100% burn-in test, ensuring stable and long-term performance in mission-critical environments.
