Long Range Communications
The MDS SD Series of industrial-strength data communications
products offer secure, reliable, long distance transmission of data for
your mission critical applications. The higher transmit power used by
the SD to operate in the licensed 400 MHz (SD4) and 900 MHz (SD9)
frequencies, results in a wide area of coverage. The SD's exceptional
receiver sensitivity allows for deployment in applications where
obstructions, such as trees and buildings, would limit the effectiveness
of other wireless devices. The combination of these features results
in the ideal data acquisition product for error free, long distance
communication.
IP/Ethernet and Serial Communications
SD Series are cost-effective solutions to wirelessly transport polled IP/
Ethernet, and/or serial data from attached PLCs and RTUs, over long
distances, to SCADA systems.
The SD optimizes the use of narrow radio channels and increases the
throughput available for data traffic. This results in a higher usable
data speed that benefits Ethernet SCADA applications.
Low Power Consumption
The ability to power a remote wireless device using solar power not
only makes the communication system more resistant to failure, but
it also adds installation and application flexibility. SD4 is one of the
lowest power consumption Ethernet radios available for long range
SCADA applications allowing for solar powered operation.
Additionally, sleep mode allows the SD4 to temporarily disable unused
circuitry saving energy and reducing the size of the batteries needed
to operate in a remote location, for longer periods of time, when direct
sunlight is not available.
Backward Compatibility
MDS SD Series radios can be directly added to existing MDS x710 and
x790 systems, providing both "drop-in" compatibility for expansions and
replacements, and adding Ethernet support. Backward compatibility
preserves your investment and allows a smooth transition from a
serial based SCADA infrastructure to IP/Ethernet without disrupting
day-to-day operations.
