Building Automation

The benefits of AS-Interface – such as the simple, cost-saving installation and high degree of flexibility – have now established themselves in building automation. Numerous companies are already using the AS-i installation system, for example for controlling fire and smoke dampers, shutter drives or heating and cooling ceilings using analog output modules. Damper drives with flow regulators can be connected to the controller through the MP-Bus gateway. It is also possible to process EnOcean signals from wireless pushbuttons and sensors over AS-i. During your planning and application implementation phases we can be at your side and are open to application-specific special solutions.

Connection

Under normal conditions (no bus termination or repeater), the permissible total length of the AS-i segment is max. 100 m. The calculation should take into consideration that the length of the connection cable (round cable) for each connected passive distributor must be doubled.

In the case of the active distributors (AS-i slaves) however only the one AS-i profile cable is counted.
