Belden introduces EIB cables approved by Konnex

September 2011 Enclosures, Cabling & Connectors

To install and operate a building’s management systems requires a wide range of technologies of different complexities. The control, monitoring and optimisation of the various functions and services include heating and cooling, ventilation, lighting and often even the management of electric appliances.

The basic control technologies have been in existence for some time. Systems are available in various degrees of complexity, ranging from the timer controlled water heater or thermostatic radiator valves (TRVs), to the so-called ‘intelligent houses’ which manage, according to pre-arranged efficiency criteria, everything from safety and security systems to air conditioning, and from lighting and ventilation systems to telematic services and domestic appliances.

Konnex & EIB

The Konnex Association was founded in May 1999 by the members of the following associations:

* BatiBUS Club International (BCI).

* European Installation Bus Association (EIBA).

* European Home Systems Association (EHSA).

Its main objective is to promote the newly- defined ‘single-standard’ for fieldbus applications in homes and buildings.

Standard offering from a registered manufacturer

This standard, approved by Cenelec in 2003 as the EN 50090 standard for Home and Building Electronic Systems, is based on the well established technology of EIB and enlarged with configuration mechanisms and physical media from BatiBUS and EHSA.

EIB is user-friendly and simple, the physical layer is extremely easy to install with a remote power supply network and a totally open topology. One single EIB cable running throughout the building is all that is required to handle all the applications. This cable also powers the EIB sensors.

For ease of identification, every module of the installation is identified by a selected address by means of either drum wheels, dip switches or keyboards with displays. Bus, star, ring, tree or any other combination can be installed as required, so this flexible architecture makes the system easy to extend. If the premises or the functions are modified, simply change the address list or connect an additional component to the bus.

The bus communication is based on a screened twisted pair cable design and is available in 1 and 2 pair configurations as well as an LSNH version for use in public areas. Belden cables are approved and registered by Konnex.
