AS-Interface Modules

Bihl+Wiedemann offers a wide variety of ASi modules, all of which are compatible with the current ASi-3 resp. ASi-5 standard. These are equipped with a varying number of inputs and outputs, offering the right module for every application. Special requirements such as sensors powered by ASi or external voltage (AUX) are never a problem. The large selection of analog modules reflects the commitment to offering the right module for any application or analog signal. Of particular interest are high-resolution 16-bit analog modules or modules for exceptionally fast transmission of analog values.

With the ASi modules with integrated IO-Link masters from Bihl+Wiedemann intelligent IO-Link sensors and actuators can now be easily incorporated into ASi – exactly there, where they are needed. The IO-Link sensors can be easily parametrized using the configuration tool from Bihl+Wiedemann.

Circuit board modules enable sensor and actuator OEMs to easily design ASi solutions by using a fully engineered and certified ASi module board that can be directly integrated in the device. Bihl+Wiedemann offers a wide range of PCB modules, available with various connection options as well as potted or unpotted. Upon request, Bihl+Wiedemann can even offer cost-effective modified versions or new developments based on our flexible kit system.

The benefits of AS-Interface such as the simple cost-saving installation and the high degree of flexibility are now established advantages in building automation. Numerous companies are already using the ASi installation system to control fire and smoke dampers, shutter drives, and heating and cooling ceilings using different modules, e.g. analog output modules. Damper drives with flow regulators can be connected to the PLC through the MP-Gateway. It is also possible to process EnOcean signals from wireless pushbuttons and sensors over ASi. During the planning and application implementation phase of your project, we can be at your side and will gladly provide application-specific solutions.

ASi makes full use of its strength in material handling technology. The motor modules for roller drives from Bihl+Wiedemann allow 24V motors to be controlled directly through ASi without the need for an additional control device. The speed of any drive roller can be controlled from a central location. The modules also use the braking energy of the rollers. Module inputs detect signals from sensors installed along the conveyer.

In addition to motor modules, Bihl+Wiedmann also provides remote solutions for controlling VFDs, an essential prerequisite for implementing modern system structures.
