The SEL-2730M Managed 24-Port Ethernet Switch is built specifically for harsh environments, the SEL-2730M reliably supports high-speed control, real-time automation, and SCADA traffic. The SEL-2730M withstands vibration, electrical surges, fast transients, electrostatic discharge, and extreme temperatures (–40° to +85°C). It meets or exceeds IEEE 1613 (Class 2) and IEC 61850-3 communications standards for networking devices and drops no packets during rigorous testing. The fit-for-purpose design minimizes printed circuit boards (PCBs) and interface points, resulting in greater reliability. Optional conformal coating ensures excellent contaminant resistance. With no fans or other moving parts, the SEL-2730M employs the most robust technology available for demanding applications.
