High-Speed Serial Ports
Communicate with serial devices using the six high-performance serial ports, capable of EIA-232, EIA-422, and EIA-485 signaling at data rates as high as 921 Kbps. Each port has full RTS/CTS and DTR/DSR signaling and true hardware flow control. Large buffers enable high throughput with minimum CPU loading. +5 Vdc Port Power
Simplify cabling and eliminate external power supplies for devices, such as fiber-optic transceivers and modems, by powering them directly from the SEL-3390S8 Serial Adapter’s ports. IRIG-B Time Synchronization
Synchronize the computer system clock to a demodulated IRIG-B source. Provide IRIG-B output to all ports on all SEL-3390S8 Serial Adapters in the computer system. Conformal Coating (Optional)
Protect circuitry from hazards, such as chemicals, vibration, moisture, salt spray, humidity, fungus, and corrosion, with this durable protective coating, extending the working life of the PCB and components. Reliability
Apply in harsh substation environments. The SEL-3390S8 exceeds IEEE 1613, IEEE C37.90, and IEC 60255 protective relay standards. The card provides reliable operation from –40º to +85ºC (–40º to +185ºF) and is backed by SEL’s ten-year warranty and highly rated technical support.
