The Moxa EDS-516A Series are rugged 16-port managed Ethernet switches designed for high-reliability industrial networking applications. Featuring Turbo Ring and Turbo Chain technologies (recovery time < 20 ms for up to 250 switches), along with STP, RSTP, and MSTP support, they provide fast redundancy and enhanced network availability.

These switches offer strong security with IEEE 802.1X, HTTPS, SSH, SNMPv3, and TACACS+, ensuring protected access in mission-critical environments. Flexible network management is provided via web browser, CLI, Telnet, serial console, Windows utility, and Moxa’s MXstudio. Versions for extreme environments (-40 to 75 °C) are also available.
