Use the standard computing platform to develop an application-specific system for harsh environments in industrial, utility, and commercial facilities.

Robust hardware design: no moving parts, no rotating hard drives, no fans, and no vent holes. Improve reliability with the SEL-3351 offering a Mean Time Between Failures (MTBF) of at least five times that of typical computers with moving parts. System incorporates highly reliable SEL power supplies with demonstrated MTBF of 5,000 years.

Conforms to IEEE C37.90 and IEC 60255 Protective Relay Standards and IEEE 1613 Standard for Communications Networks in Substation.Install the SEL-3351 in harsh environments, including 15 kV electrostatic discharge, fast transient, radiated emissions, overcurrent, dielectric strength, and pulse magnetic field disturbances.

Multiple I/O ports: 4 USB 1.1, dual fiber 10/100 Mbps Ethernet, and up to 16 EIA-232 ports. A choice of I/O ports allows direct connections to various local peripherals and high-speed network interfaces.

Windows® XP Professional operating system provides flexibility and functionality. Standard operating system, along with SEL and third-party software, presents customers with the ability to tailor the computer for specific applications.

Wide power supply ranges: 24/48 Vdc; 48/125 Vdc or 120 Vac; and 125/250 Vdc or 120/240 Vac. Wide supply ranges, without external inverters, make the SEL-3351 suitable for multiple applications.
