Insertion circuit unit especially for low voltage for field bus systems has recognition and evaluation system with coded groups and a recognition signal for each level

摘要

An insertion circuit, especially for low voltage, comprises a clearly defined insertion level (1,1',1'') in a built-in module (2,2',2'') with a code group unit (4,4',4'') producing and/or influencing a recognition and evaluation signal. An independent claim is also included for a process for the above unit.
