The worldwide STANDARD for home and building control




The hardware solution KAIphys revolutionizes the KNX TP Physical Layer.

KAIphys is the first KNX interface based on standard components, available for all users, without ASIC. KAIphys is a superior solution that enables high flexibility in usage combined with a high level of signal processing quality, a very wide range of provided energy from the bus. This original product allows cost effective KNX solutions. The fact that no custom specific ASIC is necessary and the possibility of choosing among various options in different modules allows an extraordinary potential for stream lining the hardware design of your future products. KAIphys offers maximum performance combined with high flexibility.
The innovative circuit is the hardware component of the technology platform KAI (KNX Advanced Interface) for KNX enabled bus devices. KAIphys, together with KAIstack forms the basis for complete KNX devices. Hardware and software components of KAI can be adapted according to given conditions.

KAIphys provides you with a chance to easily replace your presently existing solution in order to improve technical performance and optimize product costs. KAIphys is KNX certified.
