KNX

KNX is a worldwide standard for intelligent building control and automation. The KNX protocol is the world’s only truly open standard (ISO/IEC 14543-3), independent from any one manufacturer and regulated by the KNX Association of Brussels. KNX is totally interoperable between different manufacturers and products, which means only one bus network is required for your intelligent building control.

KNX is based on an event driven, distributed intelligence architecture. There is therefore no central computer or controller, but rather each device (light switch, thermostat, etc) has a tiny microcontroller that is capable of sending and receiving commands as and when an event occurs (eg. a light switch is pressed).


A single 2 core KNX cable is used to link KNX devices using a free topology (star, daisy-chain, etc). Thousands of devices can be linked on the same system. Most KNX devices are powered from the same bus cable – eliminating the need for eternal power supplies. The voltage on the KNX bus is 29 VDC SELV– which means it is not considered dangerous if accidentally touched.



A KNX solution makes the installation future-proof, as both the cabling and the software are easily reconfigured, making them adaptable to the changing demands of the building. KNX systems are both cost effective and energy efficient as it offers unprecedented durability and flexibility, and the levels of control that the system and its specific products offers establishes a generalized energy-saving trend.
