Bihl+Wiedemann offers a wide variety of AS-i modules. 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 AS-i or external voltage (AUX) are never a problem. The large selection of analog modules reflects the commitment to offering the roght module for any application or anaog signal. Of particular interest are high-resolution 16-bit analog modules or modules for exceptionally fast transmission of analog values.
Circuit board modules enable sensor and actuator OEMs to easily design AS-i solutions by using a fully engineered and certified AS-i slave 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 AS-i installation system to control fire and smoke dampers, shutter drives, and heating and cooling ceilings using different slaves, 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 AS-i. During the planning and application implementation phase of your project, we can be at your side and will gladly provide application-specific solutions.
Special requirements usually demand special function modules. Bihl+Wiedemann's product offering has the right standard solutions for you, such as AS-i/AS-i couplers or high-speed counter modules. Naturally, we can also provide custom solutions for you application. We recommend discussing your requirements with one of our specialists.
Bihl+Wiedemann offers a range of control and signaling devices based on innovative housings. Standard products are available from stock. Upon request, a housing with one or two openings can also be equipped with any of the common control and signaling devices (lights, buttons, illuminated buttons, key switches, selector switches, E-Stops, etc.) The control and signaling devices are designed to mount onto 40mm extruded rail, but can also be attached using a mounting clip. The AS-i connection is made by using a convenient M12 connection. For safety applications we also offer a safe AS-i E-STOP switch module.
AS-i 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 AS-i 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.
