The Moxa EDS-516A Series are 16-port managed Ethernet switches built for mission-critical industrial networking. Designed to deliver high network reliability, these switches integrate advanced redundancy protocols such as Turbo Ring and Turbo Chain (recovery time < 20 ms with 250 switches), along with STP/RSTP/MSTP, ensuring uninterrupted network operations.

With secure management through HTTPS, SSH, SNMPv3, and IEEE 802.1X, they offer strong access control, while industrial protocol support (EtherNet/IP, Modbus TCP, PROFINET) ensures compatibility with factory automation systems. Web browser, CLI, Telnet, serial console, and MXstudio provide flexible configuration and diagnostics.

Wide temperature models (-40 to 75°C) make these switches suitable for harsh environments in power, transport, and maritime sectors.
