EKI-2525M is industrial-grade Ethernet switches that enable you to expand your industrial network fast and cost-effectively. The EKI-2525M has four 10/100 Mbps Ethernet ports, and additionally the EKI-2525M provides one or two multi-mode fiber-optic port. Using fiber-optics, you can prevent noise from interfering with your system and supports high-speed (100 Mbps) and high-distance (up to 30 km) transmissions. EKI-2525M has industrial-grade designs, assuring high reliability and stability in harsh environments, making it a robust bridge between enterprise fiber-optic backbones and Ethernet devices. EKI-2525M includes a switch controller that can automatically sense transmission speeds. The RJ-45 interface can also be auto-detected,, so MDI or MDI-X is automatically selected and a crossover cable is not required. All the Ethernet ports have memory buffers that support the store and forward mechanism, assuring all data is transmitted properly.
