Rugged Computing Platform

Dependable Computation for Critical Infrastructure

SEL computing platforms are built to withstand harsh environments in utility substations, industrial control systems, and automation systems. Industrial computer systems require 24/7 availability and ease of service when necessary. SEL computing platforms are designed with a focus on reliability, availability, and serviceability (RAS). By eliminating all moving parts, including rotating hard drives and fans, and using error-correcting code (ECC) memory technology, SEL computing platforms achieve a mean time between failures (MTBF) of more than 300 years.* Designed, manufactured, and tested to the same IEC standards as our protective relays, every SEL computing platform is backed by a standard worldwide, ten-year warranty.

*This MTBF metric was calculated in December 2024.

Versatile and Reliable Form Factors

SEL offers a range of hardware options, including a standard 19-inch rack-mount form factor as well as a compact surface-mount form factor. All SEL computing platforms can run a Microsoft Windows or Linux OS or the SEL Blueframe application platform. SEL also offers optional PCIe expansion cards, power supplies, and monitors.

Designed and Tested to the Highest Standards

SEL computing platforms:

  • Feature no fans or moving parts.
  • Use the most reliable memory and storage available—ECC memory and single-level cell (SLC) SSDs.
  • Are designed and tested to exceed the rigorous industry standards required for harsh operating environments. Our platforms:
    • Absorb up to 15 g of impact.
    • Tolerate up to 15 kV of ESD.
    • Resist large electromagnetic fields and radio frequency interference.
    • Offer an operating temperature range that spans from –40°C (–40°F) to as high as +85°C (+185°F), depending on the specific model.
    • Have up to 95 percent relative humidity resistance.
    • Are immune to effects of corrosion with the conformal coating option.

Industry-Leading Warranty

While almost all industrial computer manufacturers provide a two- or three-year warranty, SEL computing platforms provide a standard ten-year, worldwide warranty.
