Moxa EDS-408A-SS-SC , 6 10/100BaseT(X) ports, 0 to 60°C

The EDS-408A-SS-SC is an industrial-grade managed Ethernet switch featuring 8 ports: 6 Fast Ethernet RJ45 ports and 2 single-mode SC fiber ports. This model is designed for industrial automation scenarios that require high network availability, fiber connectivity for long distances, and reliable device management.

With support for Turbo Ring and Turbo Chain (< 20 ms recovery time), STP and RSTP, the switch ensures robust redundancy. It includes a full set of Layer 2 management features such as SNMPv3, VLANs, port mirroring, DHCP, and industrial protocols like EtherNet/IP and Modbus TCP.

The switch is enclosed in a durable IP30-rated metal housing, suitable for an operating temperature range of -10 to 60 °C. With its wide voltage input range and a wealth of certifications, the EDS-408A-SS-SC is ideal for deployment in power grids, transport systems, and critical automation networks.
