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.
Bihl+Wiedemann offers the right module to collect and process any safety input signal. Both enclosure-mount (IP20) and field-mount(IP67) modules are available. From a single safety input or output to safety multi-I/O modules we offer the right ASi module for your requirementes. Many of our modules also include conventional outputs for non-safe signals.
Up to 4 analog signals with 4 ... 20 mA or 0 ... 10 V can be connected to the analog input/output modules or Pt100 or thermocouples can be processed. The resolution of the analog values can be selected with 14 bytes or with 12 bytes for fast transmission. Bihl+Wiedemann offers a wide range of ASi or AUX powered analog modules in IP20 and IP67, which cover a variety of applications.
The ASi-5 counter modules contain numerous functions, such as frequency and period duration measurement as well as a 32 bit value range, which can be selected alternatively to the fast transmission of 4 independent 16 bit counter values in 1.27 ms. All ASi-5 counter modules work with counter frequencies up to max. 250 khz.
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.
Active distributors ASi from Bihl+Wiedemann allow you to make any sensor or actuator AS-Interface capable. Even modules without their own ASi terminal can be easily integrated into an existing ASi network using these active distributors ASi. Other features include individually configurable connection options using M8 or M12 connectors, flying leads or push-in terminals to conform to the customer’s application, as well as a compact form factor, making them ideal for use in cable ducts.
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.
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 ASi connection is made by using a convenient M12 connection. For safety applications we also offer a safe ASi E-STOP switch module.
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.
