ABSTRACT:
The present invention relates to the industrial field of wiring apparatus for cables and in particular to a connecting system for cables in intrinsic-safety industrial instrumentation boards. Directly on the assembling board where the intrinsic-safety modules for the protection of the process control systems are allocated, a plurality of connecting modules of the cross-wiring type are disposed to a card on which the intrinsic-safety modules relating to various protection devices are also disposed. In this manner all connecting cables coming from the various sensors distributed in an industrial plant can converge to this card in order to be sent to a central processing unit in a homogenous typology. The connecting modules are implemented on each card depending upon the plant extension and the amount of sensors present thereon.
