The EDS-308 Series by Moxa comprises rugged unmanaged 8-port Ethernet switches designed for industrial networking. Equipped with a built-in relay output, these switches provide real-time alerts for power failures and port disconnections, helping ensure operational reliability in critical environments. They also offer broadcast storm protection to maintain stable network performance under heavy traffic.

Certified for hazardous locations under Class 1 Division 2 and ATEX Zone 2, the EDS-308 models are well suited for challenging applications in manufacturing, transportation, and energy sectors. Models with extended temperature capability (-T) are rated for reliable operation from -40 to 75 °C. A compact form factor and DIN-rail mounting allow for easy deployment in control cabinets.
