IBT Ing. Buro Bronnimann Thun Logo

As Embedded Systems specialists established in 1993 with a focus in Open Protocol Solutions we support primary companies in doing their own product designs for LonWorks, IP, IzoT, BACnet, ModBus DALI Ed. 2 or similar solutions. Many designs of big players use our communication design. In addition, we develop our own niche products and use external manufacturing resources for stock building.

Participation in IEC (and other) expert groups ensures our state of the art expertise in this dynamic market place.
IBT offers complete solutions for design and manufacturing including supporting product life cycles in a sustainable way.
