Multiple signal transmission device

摘要

A multiple signal transmission unit includes input/output modules having top and bottom portions which are connected electrically and mechanically via a plug connection. The bottom portions are designed exclusively for the current supply of the neighboring module of a line of modules by spring contacts which pass through the bottom portions from lineup side to lineup side. These modules are in contact connection from bottom portion to bottom portion via the spring contacts, while all elements of the circuit are associated with the top portions for the control of the machines, subassemblies, and the like that are connected with the modules.
