SYSTEM MODULE FOR BUILDING ELECTRICAL INSTALLATION TECHNOLOGY AND DOOR COMMUNICATION TECHNOLOGY

摘要

The present invention relates to a system module for building electrical installation and door communication, consisting of a module lower part (2) and a functional upper part (3) detachably connected to said lower part. The module lower part (2) is used for mounting on a system support. The module lower part (2) has a cuboid-shaped base part (4), which holds a circuit carrier (6) with the electronic circuit thereof. The circuit carrier (6) has on one side two multiple contacts (7, 8) for connection of a bus line. The multiple contacts (7, 8) are electrically assigned such that they form both input pads and output pads for electrical signal processing and voltage supply. The multiple contacts (7, 8) can be accessed via openings (11) in the base part (4). The invention further relates to a system arrangement of a plurality of system modules according to the invention.
