Coupling module for connection of user module to bus conductor line

摘要

The bus conductor line can be a strip (9) or a round cable. The coupling module (1) comprises an information interface (11), via which information about the user's module (2), or about subscribers coupled to it, can be interrogated and/or information for the user's module or its subscribers can be supplied. A changeover logic for the information interface from the input to the output mode is integrated in the coupling module. The interface is located at one front side of the housing.
