 KNX IP Interface 740 wireless

The KNX IP Interface 740 wireless is a WLAN interface to the KNX/EIB bus. It can be used instead of a USB or wire-bound IP interface, e.g. for the ETS3 and ETS4. Utilising the wireless technology the installer can now move unhindered throughout the building.


The KNX IP Interface 740 wireless contains an integrated Access Point which provides the direct connection to the device via a WLAN network. It has an external 9V power supply.
