SEL-1102 Computing Platform
Mission-Critical Platform for Windows® or
Linux® Software Applications

Help your end-user customers integrate this rugged computing platform in applications that demand highest
reliability and lowest maintenance in extreme harsh environments. You can add value by installing the operating system and application software and initializing databases for specific end-user applications. The
SEL-1102 is also a comprehensive solution for internal integrators, or “super users,” with personnel capable
of installing operating systems and integrating their own systems. By eliminating all moving parts, including
rotating hard drives and fans, we have added ruggedness well beyond that of typical computers. By eliminating vent holes, the SEL-1102 significantly reduces dust buildup and foreign contaminants. You can install
operating system and applications software in internal CompactFlash® drives to customize the SEL-1102 for
specific applications. Every SEL-1102 comes with our unprecedented 10-year, worldwide SEL warranty.

Increased Reliability. The SEL-1102 is designed and built to operate reliably in harsh environments,
conforming to IEEE C37.90 and IEC 60255 Protective Relay Standards and the IEEE 1613 Standard
for communications networks in substations. The computing platform meets or exceeds specification
for vibration, electrostatic discharge, fast transient, radiated emissions, overcurrent, dielectric strength,
and pulse magnetic fields disturbances. The SEL-1102 uses the same power supply as SEL protective
relays, with observed Mean Time Between Failure (MTBF) of 5,000 years. The computing platform
eliminates all moving parts, including fans and rotating hard drives, which are typical sources of computing system failures.
Improved Performance. An independent watchdog microcontroller complements the system microprocessor. The microcontroller detects and alarms for problems, detects operating system interruptions, and restarts the system microprocessor.
Flexible System Interconnection. A choice of 4 USB 1.1 ports and up to 16 EIA-232 ports offer optimized I/O connections to various peripherals.
Wide Power Supply Ranges. Three power supply types, operating over wide supply voltage ranges,
provide flexibility in various system applications and eliminate the need for inverters.
High-Speed Network Access. Dual fiber and/or a copper 10/100 Mbps Ethernet connection support
high-speed connection to the network.
Time Synchronization. The SEL-1102 distributes incoming IRIG-B to connected devices.
