- Gigabit High-Speed Ethernet Ports
Communicate over Ethernet connections using the four independent Gigabit Ethernet ports capable of 10, 100, and 1000 Mbps connection speeds. Each port has a unique media access control (MAC) address, allowing connections to as many as four independent Ethernet networks.
- Copper and Fiber-Optic Connections
Connect to copper 10/100/1000BASE-T and fiber-optic 100BASE-FX and 1000BASE-X networks. SFP fiber-optic modules enable flexibility and mixed-network connections. Three different port configurations are available: four RJ45 copper ports, four LC SFP fiber-optic ports, or two RJ45 and two SFP ports.
- Conformal Coating
Protect circuitry from hazards, such as chemicals, vibration, moisture, salt spray, humidity, fungus, and corrosion, with this durable protective coating that extends the working life of the PCB and components.
- Reliability
Apply in harsh substation environments. The SEL-3390E4 exceeds IEEE 1613, IEEE C37.90, and IEC 60255 protective relay standards. The card provides reliable operation from –40º to +75ºC (–40º to +167ºF) and is backed by SEL’s ten-year warranty and highly rated technical support.
