What KNX means?

What KNX means?

KNX is technology which controls the automation of integral functions of any residential, commercial or industrial building such as HVAC, lighting systems, multimedia, security, energy management and more.

What is the KNX bus voltage?

24 V
In KNX TP the bus cable supplies all bus devices with both data and power. The rated voltage of the bus system is 24 V, while the voltage provided by the power supplies is 30 V.

What is EIB electrical?

The European Installation Bus (EIB) allows all electrical components to be interconnected through an electrical bus. Every component is able to send commands to other components, no matter where they are.

What is a KNX sensor?

The KNX rotary sensor is used for controlling dimming, switching, and blind actuators, as well as for adjusting the target value of a temperature controller. The rotary sensor has three extension inputs for connecting conventional, potential-free contacts of switches, buttons, and magnetic contacts.

When was the EIB and KNX specification published?

The KNX specification was published by the newly set-up KNX Association in the spring of 2002. It is based on the EIB specification, supplemented with new configuration mechanisms and communication media originally developed by Batibus and EHS.

How does the ABB I-Bus EIB / KNX work?

The connection to the ABB i-bus® EIB / KNX is implemented via bus connecting terminals. The setting of the parameters is undertaken with the Engineering Tool Software ETS2 (from version V1.3) or ETS3. The rights and the copyright to this manual are exclusively the property of ABB STOTZ KONTAKT GmbH.

Is the EIB / KNX shutter / blind actuator free?

The KNX® product databases are free and can be imported to the ETS (ETS3, ETS4, ETS5 and higher). EIBMARKT® GmbH Holding ( presents a new 230V EIB/KNX shutter/blind actuator 6-fold (N000303) with manual operation (mounting method DRA, modular spacings 6).

What does KNX stand for in engineering category?

KNX encompasses tools for project engineering tasks such as linking a series of individual devices into a functioning installation and integrating different media and configuration modes. This is embodied in an Engineering Tool Software (ETS) suite. A KNX installation always consists of a set of devices connected to the bus or network.
