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

The EDS-208A Series from Moxa consists of rugged unmanaged Ethernet switches with up to 8 10/100BaseT(X) ports and optional fiber connectivity via SC or ST connectors, supporting both multi-mode and single-mode fiber. These switches are engineered for challenging environments such as transportation systems, industrial automation, maritime operations, and hazardous zones.

With redundant 12/24/48 VDC power inputs, IP30-rated aluminum housing, and wide operating temperature support (-40 to 75 °C for -T models), these units are optimized for high-reliability applications. DIP switches allow for configuration of broadcast storm protection, and each unit undergoes 100% burn-in testing to ensure industrial-grade durability.
