Brewing terms “Mash”, “Clarify” and “Brew” are shown in big letters above the brewing kettle at the Bitburger brewery, indicating the current stage of the brewing process. The challenge here lies in the fact that the process itself isn’t actually visible, but the various different brewing stages still need to be reliably coordinated by means of the reception, processing and emission of signals.
When it was time to replace the brewery’s old remote I/O system, Bitburger maintenance employee Horst Becker got in touch with Weidmüller. The challenge consisted of installing a fieldbus coupler with the most compact dimensions possible in the smallest of spaces, while still ensuring that the system remained manageable.
Compact and self-explanatory
The value of u-remote’s sleek, single-row design and the associated simple module handling quickly became apparent to Becker and his colleagues over the course of their day-to-day work. With a width of just 11.5 mm, the solution could be integrated into the panel without taking up too much valuable space, and the electronic

modules are simple and can be replaced without any tools. “There’s no need for any complicated plans,” says Becker.
“The high humidity levels and high temperatures at the installation location are not a problem,” reports Norbert Schuster, Sales Engineer at Weidmüller. “Thanks to the sturdy housing, u-remote passed all of the tests with flying colours and met all of our expectations right from the preliminary stages.” He also mentions additional benefits such as the plug-in connector frames, the PUSH IN connection and the improved holding force of the cables. Each channel also has an LED display for quick and clear status identification.

Installation work was carried out over a long weekend when no work was being carried out at the brewery. “This meant that there was no need for any unscheduled downtime,” Becker recalls. “And the Weidmüller team was also on site to provide support at all times. The software modifications that needed to be carried out to our specific requirements were performed in no time.”
The Weidmüller solution is now used in the entire Bitburger brewing line and in the filtration stage at the Licher Privatbrauerei, a subsidiary company of the Bitburger Braugruppe. There are plans to install the system in dealcoholisation systems at additional sites and at a supplier for yeast-extraction systems in the future.
