Enables the forwarding of telegrams between different lines over a LAN (IP) as a fast backbone. The device also serves as a programming interface between a PC and the KNX bus (e.g., for ETS programming). The device supports KNX Security. As a Secure Router, it allows the coupling of unsecured communication on a KNX TP line with a secure IP backbone. Even in the interface function (tunneling), KNX Security prevents unauthorized access to the system. Supply voltage: External supply 12-24 V AC. Power consumption: under 800 mW. Operating temperature: -5 to 45 degrees Celsius. Protection class: IP 20. Protection rating: III. Dimensions (W x H x D): 18 x 90 x 56 mm.
