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

The EDS-208A Series by Moxa features rugged, unmanaged Ethernet switches with up to 8 ports, offering 10/100BaseT(X) RJ45 and optional 100BaseFX fiber ports (multi/single-mode, SC/ST). Designed for use in hazardous zones (Class I Div. 2, ATEX), transportation systems, and marine applications, the switches ensure robust networking in industrial settings.

With dual redundant 12/24/48 VDC power inputs, IP30 aluminum housing, and DIP switches for broadcast storm protection, the switches guarantee reliable operation. -T models support a wide temperature range of -40 to 75 °C, suitable for extreme environments.

All units are fully burn-in tested and meet industry compliance for continuous 24/7 deployment in automation and control systems.
