450SR
Data Radio
Download a detailed data sheet for this product 450SR datasheet
The 450SR range of Data Radios have been designed specifically for the
SCADA telemetry point to point and multipoint market.
The 450SR remote transceiver is a high quality, miniature, full featured, 5 watt half duplex radio transceiver,
designed specifically for narrow band OEM digital data transmission applications which employ filtered baseband
or audiosubcarrier data modulation.
- Low power consumption - reducing power supply (solar) costs.
- Miniature size - reducing cabinet size and in turn cost.
- Full 1 Watt @ 7.2 V and 5 Watts @ 13.8V D.C. supply.
- Minimal alignment (human intervention)- only three (3) internal adjustments.
- Excellent specification and performance figures.
- User programmable by PC software - broad band frequency selection, transmitter
power output, digital mute setting, PTT timer etc. allowing immediate installation.
- Fast Tx/Rx switching - offering greater efficiency and inturn greater
remote populations.
- Serial Communications Interface OR Analogue Monitor Outputs of critical
parameters for remote diagnostics monitoring.
- Wide audio bandwidth and good group delay characteristics, making it
ideal for many digital modulation types.
- Built in time out timer, brown out reset, and watchdog for lock up free
operation.
- Intelligent processor controlled digital temperature compensation, low
aging quartz reference for long term stability.
- Programmable digital tuning (alignment) of frequency reference for ease
of long term service.
- Suitable for operation in the UNLICENSED spectrum band plan.
- Over Voltage transorb protection.
- Wide temperature range -10 to 600C with over temperature transmitter
power foldback.
- Digital modulation capability - true digital radio capable of higher
data rates 4800/9600bps etc.
- Use of Microwave Stripline Technology to minimise components and the
likelihood of failures.
- Excellent electrical noise immunity - minimal if any effects from external
equipment.
- Designed and manufactured in Australia
- Complete product housed in a small metal enclosure providing excellent
heat dissipation and shielding.
- All connections extend from a single 15 way DMin connector for simple
connection
Plug In Modules
The SR Series of miniature data radio's have been designed to accommodate
a range of internally fitted plug in ancillary modules which include audio pre-de-emphasis modules, 1200/2400/4800bps
RS-232 interface modules.See
