The Advantech EKI-2428G-4CA is a high-performance unmanaged Ethernet switch designed for core and edge industrial networking. Featuring 24x Gigabit copper ports and 4x RJ45/SFP combo slots, the switch delivers a total capacity of 56 Gbps with a forwarding rate of 41.7 Mpps, ensuring reliable wire-speed transmission across demanding applications.
Ideal for expanding industrial and enterprise backbones, the EKI-2428G-4CA provides flexible fibre expansion through its SFP combo ports, supporting transmission distances up to 110 km (depending on SFP). Auto MDI/MDIX, auto-negotiation, and full/half-duplex modes make installation straightforward, while rackmount form factor with solid mounting kits ensures easy deployment in 19-inch cabinets.
The switch is built with a rugged IP30-rated metal housing and operates reliably in standard industrial environments from 0°C to +60°C. It includes redundant safety and EMC certifications (CE, FCC, EN55032 Class A, EN55024, EN61000), making it suitable for deployment in manufacturing networks, smart infrastructure, transport hubs, and data aggregation systems.
Powered by 100–240 VAC (50/60 Hz), the EKI-2428G-4CA offers a reliable and scalable unmanaged solution for organisations looking to expand bandwidth and integrate copper and fibre links seamlessly.
