The OPUS 21d sets standards for user-friendliness. This model is characterised by a purist approach to operation, bringing unusual simplicity to complex and demanding operational and settings functions. Equipped with the trusted Wachendorff operating system, the OPUS 21d also has a quick-start function. Standalone or fitted into a dashboard, the 21d is a true all around unit that offers a wide range of practical application options. Our customers value its reliability and safety in everyday use. After all, when nothing else works any more, everything can be easily controlled from the OPUS 21d. For this reason, this device is particularly popular for use in construction and municipal machines.
