Abstract
The input and/or output device for process data has a mounting rack (1), as well as a plurality of modules (2) fastened on the mounting rack (1). A process connector (4) can be inserted into each of the modules (2) on the front side in each case. Each module (2) has a circuit board (17) which is arranged in a housing (8), as well as a terminal strip (18) which is connected non-positively to the process connector (4). The terminal strip (18) serves to receive contact pins (26) which interact with contacts of the process connector (4). The input and/or output device is intended to demonstrate a high degree of operational reliability even in the case of a high level of mechanical and electromagnetic stresses. This is achieved in that the module housing (8) is predominantly formed from metal plate and has lugs (21, 22, 23) formed out of the metal plate which serve to carry the circuit board (17), some of which lugs are electroconductively connected to a conductor track (32) of the circuit board (17), and in that the module housing (8) is in contact with a metal part of the mounting rack (1) which is at ground potential.
