The SEL-1102 is a rugged computer built to withstand harsh environments in utility substations, and industrial control and automation. The SEL-1102 comes without an operating system, allowing you to load your operating system of choice such as Linux®. Designed and manufactured to the same standards as our protective relays, the SEL-1102 has no moving parts, and withstands -40° to +75°C. With an MTBF of 10 times over other industrial computers, it is backed by SEL’s no-questions-asked, worldwide, ten-year product warranty.
The Firmware IDs for older versions of the firmware can typically be found in Appendix A of the instruction manual.
