Moxa EDS-208A Series – Compact 8-Port Ethernet Switches for Industrial Environments

The EDS-208A Series from Moxa delivers rugged and compact unmanaged Ethernet switches with up to 8 ports, including 10/100BaseT(X) and optional 100BaseFX fiber (SC/ST, multimode/singlemode). With IP30 aluminum housing, redundant 12/24/48 VDC inputs, and wide temperature support (-T models up to -40 to 75°C), these switches are perfect for use in harsh environments such as transportation, energy, marine, and hazardous zones.

All models support auto negotiation, MDI/MDI-X, full-/half-duplex, and include broadcast storm protection via DIP switches. Fully certified for ATEX Zone 2, Class I Div. 2, EN 50121-4, NEMA TS2, and DNV/LR/ABS/NK, they are ready for almost any industrial deployment.
