The EDS-208A Series from Moxa consists of compact unmanaged industrial Ethernet switches with 8 ports, specifically engineered for reliable networking in rugged industrial conditions. Supporting 10/100BaseT(X) and 100BaseFX via SC or ST connectors, depending on model, these switches feature redundant 12/24/48 VDC power inputs, robust IP30-rated aluminum housings, and certifications for hazardous, transportation, and maritime environments. With a wide operating temperature range of -40 to 75°C (for -T models), they are designed for durability in extreme settings. DIP switches allow flexible configuration of broadcast storm protection.
