The EDS-408A-SS-SC-T is an industrial-grade managed Ethernet switch with a total of eight ports, including 6 Fast Ethernet RJ45 ports and 2 single-mode SC fiber ports. Designed for harsh environments, this model supports an extended operating temperature range of -40 to 75 °C, making it ideal for outdoor deployment, transportation systems, and energy distribution networks.

High network reliability is ensured through redundancy technologies such as Turbo Ring and Turbo Chain (recovery time under 20 ms), as well as RSTP and STP. It supports industrial communication protocols including EtherNet/IP and Modbus TCP. With VLAN support, port-based QoS, IGMP snooping, and strong security features like HTTPS, SSH, SNMPv3, and Port Lock, the switch offers secure and efficient network management.

The rugged IP30-rated metal housing, redundant power inputs, and comprehensive industrial certifications make the EDS-408A-SS-SC-T a reliable solution for mission-critical automation networks.
