The EDS-408A-T is an industrial managed Ethernet switch with 8 Fast Ethernet ports (10/100BaseT(X)) designed to operate in harsh environments, offering an extended temperature range of -40 to 75 °C. It is an ideal entry-level solution for applications in power systems, transport infrastructure, and industrial automation.

With built-in redundancy features such as Turbo Ring and Turbo Chain (recovery < 20 ms), and support for RSTP and STP, the EDS-408A-T ensures reliable network availability. It also supports industrial communication protocols like EtherNet/IP and Modbus TCP. Other features include VLANs, IGMP snooping, port mirroring, and robust security and management tools, all within a compact, rugged IP30-rated metal enclosure.
