SEL-2742S SDN шилжүүлэгч

The SEL-2742S is a 12-port DIN-rail- or surface-mounted network switch for industrial environments. The SEL-2742S combines with the SEL-5056 Software-Defined Network Flow Controller to improve LAN cybersecurity with a deny-by-default approach to network traffic forwarding. Software-defined networking (SDN) streamlines network management, change control, and data collection for cybersecurity audits.

The SEL-2742S is designed and built for operation in harsh environments, meeting IEEE 1613 requirements. The SEL-2742S operates in –40 to +85°C (–40 to +185°F), and dual power supply connections provide connectivity to primary and backup power sources.
