The SEL-2740S is the industry’s first field-hardened software-defined networking (SDN)-enabled switch and is designed to improve Ethernet cybersecurity and performance for operational technology (OT) applications. The SEL-2740S and the SEL-5056 Software-Defined Network Flow Controller give you path- and packet-level control of your communications flows, which eliminates common cybersecurity vulnerabilities in traditional LANs and improves failover performance to less than 100 μs. SEL SDN also makes it easy to more precisely manage large amounts of network traffic, making it the perfect solution for anyone transitioning to IEC 61850. The SEL-2740S is designed for the harsh environments commonly found in electric utility substations and industrial plants.
