The Moxa EDS-516A-MM-SC-T is an industrial-grade managed Ethernet switch equipped with 14 Fast Ethernet ports (RJ45) and 2 fiber-optic ports (100BaseFX, multi-mode SC connectors). Designed for use in critical infrastructure and harsh environments, the switch provides superior redundancy via Turbo Ring and Turbo Chain (recovery < 20 ms for up to 250 switches), as well as support for STP, RSTP, and MSTP.

With an operating temperature range from -40 to 75 °C and extensive Layer-2 management capabilities, this device is ideal for automation, transportation, and energy applications. The EDS-516A-MM-SC-T also supports key industrial protocols like EtherNet/IP and Modbus TCP, along with advanced security and VLAN features.
