•
Fast repairs; training and support
Translation -- A high priority
• Long-distance, high-speed, reliable, data
communications
Data Communications
Rel-Tek’s first generation technology; ‘91 - ‘96
Enter the “Link” Card
• Rel-Tek’s second generation; ‘96 - ‘07
Latest B-LINK Repeaters
• Rel-Tek’s 2008 communication technology
The “B-LINK”
“DX-LINK”
No need for costly optical fibers
Handles 20mile mines at
19.2KB with
inexpensive
twisted-pair
cables

Millennia-FT ~ Version 7.0, PC software and advanced field
I/O hardware -- developed for very large coal mines ~
Performance test:
A longwall coal mine running Millennia-FT with 340 sensors,
180 switches and 180 controls, communicating for 20-miles on
low-cost twisted-pair cables ~ with multiple 3-mile branches
The monitoring and control execution cycle time
Previous 45 sec cycle time was cut to just 3.4
seconds.
That’s 113 data registers per second.
“FT” can avoid optical fibers
Hey Purchasing, Cancel that fiber order!
Millennia-FT™ (Flash-Telemetry) permits use of twisted-pair cables to 20-mile
distances. Millennia is “hard coded” C++ programming that is very fast.
Millennia-FT™ runs on Windows or Linux. Modbus interfacing is available.
Twisted-pair cable enables low cost installation, easy troubleshooting and simplistic
maintenance.

Results of a 13-hour test
– Diagnostic screen for one of 68
addresses in this test
Accuracy:
• Even one error would be -99.99996% reliability
• Such an error would be detected
and corrected and repeated.
• Zero data errors, 100% reliability
Speed:
• 18.4 addresses polled per second
• Each DX4404 card address
included 4-AI, 4-DI and 4-DO
• Throughput of 220 data points per
second

Pioneering products for cutting cost and
enhancing safety
MagiKal is our flagship system providing fully
automatic, hands-off sensor calibration
Includes full calibration time stamps and
logged documentation
Grqaphic displays of each sensor cal-trends
Small or large systems -- one sensor or a
thousand
Saves big -- on labor, cal-gas cost and even
extends the life of your sensors

Computer scheduling -- monthly, weekly or
daily -- and it never forgets!
Small, inexpensive tanks
handle a sensor or two for a
year or more.
Two large tanks handle a
hundred sensors for a year
