Key Features:
-
Robust hardware design: no fans,
no moving parts, ten-year warranty Improve reliability
with the SEL-1102, which has a predicted Mean Time
Between Failures (MTBF) of at least ten times that
of typical computers. An independent diagnostics
watchdog processor improves system availability
by detecting and alarming for problems, detecting
system crashes, and restarting the main processor.
Eliminate inverters by using station dc power.
-
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-1102 suitable for multiple applications.
-
Reliable substation operation—meets
IEEE C37.90 and IEC 60255 Protective Relay Standards
Install the SEL-1102 in substations instead of desktop
and rack-mount computers designed for controlled
office environments. The SEL-1102 is designed for
harsh substation environments and withstands vibration,
electrical surges, fast transients, and extreme
temperatures.
-
Separate system processor and
watchdog microcontroller enhance system performance
and availability
An independent watchdog microcontroller complements
a choice of Transmeta or Intel® system microprocessors.
The microcontroller detects and alarms for problems,
detects operating system interruptions, and restarts
the system processor.
-
Flexible solution meets value-added
resellers’ needs using computer industry standards
Load your software to meet your needs. The SEL-1102
is compatible with popular operating systems and
software, and includes expansion support for PC-104
and PC-104 Plus cards, optional IDE drives, and
memory. Includes two Ethernet ports, four USB ports,
an IRIG-B time input, and IRIG-B time outputs.
-
Configurable Label Simplifies
Product Identification
Supports configurable slide-in label for the product
name, allowing you to label it as you see fit.

Applications:
The SEL-1102 is primarily intended for sale
to value-added resellers (VARs). The value that
they add includes installing the operating system
and applications software, and initializing
databases for specific end-user applications.
Some end users are internal integrators, or
“super users,” with personnel capable
of installing an operating system and integrating
their own systems. Or, if you are an end user
that works with a third-party integrator, consider
specifying SEL-1102 hardware to your integrator.
-
Connect a video monitor,
keyboard, and mouse to provide a human-machine
interface (HMI) for alarm annunciation,
local indication, control, and configuration.
-
Connect to communications
processors in a substation to convert
relay data to a legacy protocol for a
SCADA master. Use data from SEL relays
and other devices instead of lower reliability
remote terminal units.
-
Use the SEL-5040 Power
System Report Manager to detect, gather,
and summarize relay event reports.
-
Gather time-tagged events
from relays and I/O processors to serve
as a station-wide Sequential Events Recorder
(SER). Forward data to a system-level
computer for system-wide SER.
-
Perform automatic control.
- Concentrate data from relays, communications
and logic processors, and other devices;
forward information to multiple master data
users, for example, SCADA, EMS, Power Quality,
and Equipment Maintenance systems.
- Install soft-PLC software for local automatic
control.
