With a modular control cabinet, Firm LQ reduces the variety of parts by combining conventional components into functional assemblies. Unlike conventional control cabinets, each module in the modular control cabinet contains a defined input, output and software interface. The formation of functional groups reduces machine downtimes and thus the costs that would be incurred in the event of a lengthy breakdown. Thanks to separable connections, the modules can be easily replaced. Thanks to the plug & play principle, the function groups can be installed directly on site as they are function-tested and prefabricated.
