AS-Interface Master News (02/2024)

Easy integration of Danfoss VLT frequency inverters

Would you like to connect Danfoss frequency inverters from the VLT series to AS-Interface? Simply by plug-and-play via their standard RS485 interface? Then use our ASi-5 motor module BWU4980. Simply connect the module with the two wires to the RS485 terminals in the Danfoss VLT frequency inverter, and you're done. Thanks to ASi, the power supply and communication of the module is carried out via a single cable.

About Bihl+Wiedemann

We develop and manufacture complete automation solutions – for functional safety and data communication in machines and plants. Our solutions are mostly based on AS-Interface (ASi), which is the globally standardized fieldbus system for the first level of automation.


ASi makes huge cable bundles a thing of the past, since sensors and actuators no longer have to be wired individually to the controller. Instead, the two-core yellow ASi cable by itself supplies each input and output of the device with both data and power.


We strive to help our customers successfully implement Industry 4.0 projects on the field level. Therefore, we played a major role in the development of the new ASi-5 technology.

The new ASi generation of frequency multiplex transmission allows for much faster transmission of larger data volumes and easy integration of intelligent sensors.


Our IO-Link solution based on ASi-5 enables the connection of various IO-Link devices on just one line. In contrast to comparable PROFINET solutions, it brings considerable cost advantages.


Customers from various industries benefit from our ASi solutions. The open bus system is particularly widespread in industrial automation, materials handling and mechanical engineering.
