The EDS-518A-SS-SC from Moxa is a high-density industrial managed Ethernet switch designed for extended fiber-optic networking. It features 14 Fast Ethernet ports (10/100BaseT(X)), 2 single-mode fiber ports (100BaseFX with SC connectors), and 2 Gigabit combo ports (selectable between 10/100/1000BaseT(X) and 1000BaseSFP), providing exceptional flexibility for long-distance backbone communications.

Built for rugged environments, the switch operates from 0 to 60 °C and includes advanced networking capabilities such as Turbo Ring, Turbo Chain, STP/RSTP/MSTP, VLAN management, IGMP snooping, QoS, and high-level security (HTTPS, SSH, TACACS+, RADIUS). Industrial protocol support for Modbus TCP and EtherNet/IP ensures seamless integration into automation infrastructures.
