The EDS-308 Series from Moxa offers rugged unmanaged 8-port Ethernet switches, engineered for demanding industrial environments. Featuring a built-in relay output, the switches alert engineers in case of power loss or port disconnection, enabling faster troubleshooting. Integrated broadcast storm protection ensures stable network performance under heavy load.

Certified for hazardous areas (Class 1 Div. 2, ATEX Zone 2) and maritime use (DNV), these switches meet global standards like FCC, UL, CE, and MIL-HDBK-217F. The models support standard temperature operation (-10 to 60 °C) and extended temperature ranges (-40 to 75 °C). Housed in a durable metal casing with IP30 protection, EDS-308 switches are DIN-rail or optionally wall mountable.
