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 ASi 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 ASi. During your planning and application implementation phases we can be at your side and are open to application-specific special solutions.

Passive Distributors ASi, IP67
| Figure | Type | Housing | "IP20": "IP40": Protected against solid foreign bodies having a diameter of 1.0 mm or larger, protected against access with a wire, no protection against water. "IP54": Protection against dust in damaging amounts, complete protection against contact, protection against splashing water in any angle.
Dust-tight, full protection against contact, protection against temporary immersion. | Modules with a flat housing design and with cables which exit the sides make these ideal for installation in cable ducts, cable channels, cable troughs, cable rails or cable trays. Please note the respective housing depth for your particular installation. | PUR line, oil resistant. Further connection options are available on request.
| Under normal conditions (no bus termination or repeater), the permissible total length of the ASi 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 (ASi modules) however only the one ASi profile cable is counted. | Profile cable connection | Article No. | ||||||||||||||||||||
