Moxa EDS-208A Series – Compact and Rugged 8-Port Industrial Ethernet Switches

The Moxa EDS-208A Series offers reliable, unmanaged Ethernet switches with 8 ports and optional fiber connections, tailored for harsh industrial conditions. With support for copper and fiber interfaces (SC/ST, multi-/single-mode), these switches are ideal for marine, rail, transportation, and hazardous locations (Class I Div. 2, ATEX Zone 2).

Housed in a robust IP30-rated aluminum case and equipped with dual redundant power inputs, these switches withstand extreme temperatures ranging from -40 to 75 °C (-T models). DIP switches allow broadcast storm protection to be toggled on or off, ensuring high adaptability in the field.
