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.

In order to avoid interferences in ASi-5 communication, Bihl+Wiedemann recommends the use of power supplies optimized for ASi-5/ASi-3.


30 V power supply, optimized for ASi-5/ASi-3, NEC class 2 :

The 30 V/3 A power supply is UL certified, has power limitation <100 W and is designed for use in NEC class 2 networks. It is suitable for applications with 1 power supply per ASi network. In the case of power intensive applications, Bihl+Wiedemann recommends the use of a 30 V power supply without 100 W power limitation in combination with a power limitation module (BWU4189) for each ASi network.The power supply is optimized for use with ASi-5/ASi-3 gateways and safety monitors with integrated decoupling coils (version "1 power supplies, 1 gateway for 2 ASi networks, inexpensive power supplies") and with all 24 V ASi-5/ASi-3 gateways. In order to avoid interferences in ASi-5 communication, Bihl+Wiedemann recommends the use of power supplies optimized for ASi-5/ASi-3.

Active Distributors ASi, IP67/IP20

Figure Inputs digital Outputs digital

inputs are supplied by ASi or by AUX (auxiliary 24 V power). If supplied by ASi, inputs shall not be connected to earth or to external potential.

Input voltage (sensor supply)

Electronic outputs are supplied by ASi or by AUX (auxiliary 24 V power). If supplied by ASi, outputs shall not be connected to earth or to external potential.

 

For relay outputs the relay contacts are initiated from ASi. The load circuit is powered externally as specified in the data sheet.

Output voltage (actuator supply)

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.

Flat design, installation in cable duct possible

status of in- and outputs is indicated by LEDs. In addition to that, both ASi LEDs (PWR green and FAULT red) show - as usual regarding the ASi modules - the status of the ASi modules. Uaux is indicated by a green LED.

LED status display
Connection

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.

Round cable

AB address (max. 62 AB addresses/ASi network), 2 AB addresses (max. 31 modules with 2 AB addresses), Single addresses (max. 31 Single addresses/ASi network), ASi-5 address (max. 62 ASi-5 addresses/ASi network), mixed use allowed.
For ASi modules with two ASi nodes the second Asi node is turned off as long as the first Asi node is addressed to address "0".
Upon request, ASi modules are available with specific ASi node profiles.
