The Moxa EDS-205A-M-SC-T is a rugged, unmanaged industrial Ethernet switch equipped with four 10/100BaseT(X) ports and one 100BaseFX multi-mode fiber port with an SC connector. Designed for harsh environments, it is well suited for applications that require fiber optic connectivity alongside standard copper ports.

Operating in a wide temperature range of -40 to 75 °C, with a compact aluminum housing and dual redundant 9.6–60 VDC power inputs, this switch is ideal for deployment in energy systems, railways, traffic control, and outdoor enclosures. DIP switch-configurable features like broadcast storm protection and QoS allow for straightforward, application-specific optimization.
