EKI-2525MI/2525SI are industrial-grade Ethernet switches that enable you to expand your industrial network quickly and cost-effectively. The EKI-2525MI/2525SI have four 10/100 Mbps Ethernet ports. Additionally the EKI-2525MI provides one multi-mode fiber-optic ports, while the EKI-2525SI provides one single-mode fiber-optic port. Using fiber-optics prevents noise from interfering with your system and supports high-speed (100 Mbps) and high-distance (up to 30 km) transmission.

EKI-2525MI/2525SI have industrial-grade designs, assuring high reliability and stability in harsh environments. This makes them a robust bridge between enterprise fiber-optic backbones and Ethernet devices. EKI-2525MI/2525SI includes a switch controller that can automatically sense transmission speeds. The RJ45 interface can also be autodetected, so MDI or MDI-X are automatically selected and a crossover cable is not required. All Ethernet ports have memory buffers that support the store and forward mechanism, assuring all data is transmitted properly
