Primarily, we want to be an innovative partner for our customers: using our development expertise to meet individual requirements.

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. Since 2019, for example, our ASi-5 modules have enabled simple and convenient connection of a wide range of IO-Link devices - and since 2020, cost-effective solutions for complex requirements in drive technology.

We have been among the leading providers in the area of functional safety using ASi Safety at Work for almost 15 years. We were the first to introduce ASi-5 Safety devices in 2022. With them, many safe and non-safe signals can be used under just one ASi address.

Our complete ASi product portfolio covers Master/Gateways, AS-Interface Modules, Safety Components, Bus Couplers/Master Simulators as well as in-house developed software.
