Abstract

A base module for a control-cabinet system includes a housing with a first housing face and further housing faces, the first housing face having a grid of openings. The housing has connection elements for functional modules, the connection elements each being arranged in the region of the openings of the first housing face, the connection elements comprising data connections, extra-low voltage connections and low-voltage connections. The data connections are interconnected by a data line of the base module and a field-bus connection is provided for the data line, where the data line is arranged within the housing. An extra-low voltage line and a low voltage line are arranged within the housing, where the extra-low voltage line is connected to the extra-low voltage connections and the low voltage line is connected to the low voltage connections.
