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.

千兆高速以太網(wǎng)端口
以太網(wǎng)連接使用四個(gè)獨(dú)立的千兆以太網(wǎng)端口能夠10、100溝通，和1000 Mbps的連接速度。每個(gè)端口都有一個(gè)*的媒體訪問控制（蘋果）地址，允許多達(dá)四個(gè)獨(dú)立的以太網(wǎng)網(wǎng)絡(luò)連接。
銅和光纖連接
連接到銅10 / 100 /千兆以太網(wǎng)和光纖100BASE-FX和1000BASE-X網(wǎng)絡(luò)。SFP光纖模塊使靈活性和混合網(wǎng)絡(luò)連接。三個(gè)不同的端口配置可供選擇：四個(gè)RJ45銅線端口，LC SFP光纖端口四，或兩個(gè)RJ45和兩個(gè)SFP端口。
SEL網(wǎng)絡(luò)適配器保形涂料
