Radiocrafts AS, a leading provider of compact RF modules, now expand their product line with a new module complying with the KNX-RF (Konnex over RF) specification. KNX is the only open international standard for Home and Building Control, used in Smart Home, Building Automation and Building Management Systems.
The new compact module, RC1180-KNX1, being the smallest available in the market, is designed for Home and Building Automation systems using the wireless KNX protocol as defined by the KNX Association. The embedded protocol supports KNX-RF 1.1 and KNX Ready, and can be used for unidirectional and bidirectional devices, also in battery operated systems. It conforms to EN 50090 (ISO/IEC 14543-3).

KNX is one of the leading standards for home and building control. The interest for such systems is increasing, meeting the demands for energy saving technology. Studies have shown up to 50% energy savings using KNX technology. Radiocrafts is considered as one of the leaders in Wireless M-Bus technology, and Radiocrafts is now also a member of the KNX Association. With the new KNX product series, Radiocrafts gives the customers an easy transition to Konnex with compatible products. Interoperation between Wireless M-Bus and KNX-RF is also possible using the new module.

The module operates in the 868 MHz band, using Listen Before Talk (LBT) to reduce collisions. One receiver can be linked with up to 64 transmitters, enabling very large RF networks. I can be used with S, A and E modes of installation. Among other features, the module offer automatic battery supervision and signal strength information. The KNX1 is the first feature set in a family of KNX products that will also include RF repeaters and media couplers.

The new RC1180-KNX1 is a surface-mounted high performance transceiver module measuring only 12.7 x 25.4 x 3.3 mm, and can easily be integrated into any sensor or actuator. A UART interface is used for serial communication and configuration. An antenna is connected directly to the RF pin. The RC1180-KNX1 module is certified for operation under the European radio regulations for license-free use. When used with quarter-wave antennas a line-of-sight range of 800 meter can be achieved.

“By launching the compact KNX-RF module in the market, we have again demonstrated our technological leadership in embedded wireless solutions. KNX-RF is a green technology, enabling smart building automation systems that help to reduce energy consumption. Together with Wireless M-Bus, the standard for remote energy meter reading, these are technologies promising a better future”, says Peder Martin Evjen, Managing Director.

“The trend in building automation is to go wireless due to lower installation cost, ease of use and flexibility. Building equipment manufacturers and building management system integrators can now get a complete KNX-RF solution in a small compact module form-factor that is easy to integrate into any sensor or actuator, and which significantly reduce time-to-market, development and compliance testing cost”, says Tom Sjølie, Sales and Marketing Director.
