Narrowband radio modules optimised for noisy environments

The energy efficiency of these units is another key factor. At full transmission power, they only draw 407mA of current and when sleep mode is activated their current consumption is a maximum of 2.0µA.

Their elevated performance parameters and low power operation mean that these narrowband units are suited to a wide variety of modern industrial applications - including telemetry systems, process monitoring, industrial remote controls, automatic meter reading, crane manoeuvre, logistics/asset tracking and fleet management. They cover all sub-1GHz ISM bands (169, 433, 868MHz), plus certain specific national bands (such as 444, 458 and 465MHz). Thanks to the embedded RC232 bi-directional radio protocol employed, RC17xxHP modules can support both point-to-point and point-to-multipoint operation. This is also responsible for their 128byte data buffering capabilities. The strong selectivity and advanced blocking mechanisms utilised by these units gives them heightened interference robustness.

Members of the RC17xxHP series each come in a compact surface mount package, with a footprint that measures 12.8x25.4mm. They are compliant with ETSI’s EN 300 220, EN 301 489 and EN 60950 standards. The thermally stabilised crystal oscillators incorporated into these units ensure that dependable and consistent performance is maintained across the whole of their -40 to 85°C operational temperature range.

“The superior transmitter power and receiver sensitivity, plus the frequency selectivity and blocking functionality that RC17xxHP modules exhibit gives them the attributes needed to cope with the noise present in heavy industrial application settings,” explained Gordon Serpis, Franchise Manager at Solid State Supplies. “Furthermore, their pin compatibility with other units from the Radiocrafts portfolio allows them to serve as drop-in replacements when a longer range option is called for.”
