SEL computers 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 computers are designed with a focus on RAS—reliability, availability, and serviceability. By eliminating all moving parts (including rotating hard drives and fans) and using error-correcting code (ECC) memory technology, SEL compact industrial computers have a mean time between failures (MTBF) of 100+ years. Designed, manufactured, and tested to the same quality standards as our protective relays, every SEL computer comes with the unprecedented, ten-year worldwide SEL warranty.
Versatile and Reliable Form Factors
SEL offers a standard rack-mount server-quality industrial computer and a “mount-anywhere” compact industrial computer. SEL also offers optional PCIe expansion cards, power supplies, and third-party monitors.
Designed and Tested to the Highest Standards
Industry-Leading Warranty
While almost all industrial computer manufacturers provide a two- or three-year warranty, SEL computers provide a standard, no-questions-asked, ten-year worldwide warranty.
The SEL-3360 is a Compact Industrial Computer with Intel Core i7 multicore computer with no moving parts built to keep critical processes running with the highest MTBF and longest warranty.
