Leading the Way with AS-Interface Since 1995
Bihl+Wiedemann is a leader in the field of automation and safety technology with AS-Interface (ASi). We played an important role in the development of each ASi generation. Our ASi Master was the first such system to be awarded a certificate in 1995 from AS-International e.V., the ASi organization with 300 national and international partners. We also played a pioneering role in the market launch of ASi-5 devices in 2019. The latest ASi generation now allows larger data volumes to be transmitted much faster. We have been among the leading providers in the area of functional safety using ASi Safety at Work for almost 15 years.
