Your partner for industrial communication

Our range of products and services includes our KUNBUS-IC plug-in modules of all current fieldbusses like PROFIBUS, DeviceNet, CANopen, CC-Link, and Modbus. In the field of Industrial Ethernet, we offer our customers KUNBUS-IC plug-in modules with PROFINET RT, Modbus-TCP, EtherCAT, POWERLINK, SERCOS III and EtherNet/IP.

With these plug-in circuit boards, we provide flexible solutions for all communication tasks of complex controls, operation terminals, and sensors or actuators. As a further evolution step, we also supply our customers with complete communication modules of the KUNBUS-COM series.

These are technologically similar to the KUNBUS-IC modules, but also include plug connections to the controller and to fieldbuses.

In addition to these modules developed by us, we are also active for our customers in the field of custom design. Here, communication terminals are developed exactly according to the requirements of our customers and are produced by us in Germany. This variant is more economical especially for medium-sized to larger quantities.

It can’t be easier!
