The EDS-208A Series by Moxa consists of compact, unmanaged 8-port Ethernet switches designed for harsh industrial environments. Supporting 10/100BaseT(X) via RJ45 and 100BaseFX via fiber optics (multi-/single-mode, SC or ST connectors), the switches provide reliable performance in transportation, marine, and hazardous locations. With redundant 12/24/48 VDC power inputs, IP30-rated aluminum housing, and models supporting an extended operating temperature range (-40 to 75°C), this series is ideal for demanding applications. DIP switches allow easy broadcast storm protection configuration for added flexibility in network management.
