CONNECTION MODULE FOR FIELD DEVICES IN THE EXPLOSION-PROOF REALM

摘要

The invention relates to a connection module for field devices in the explosion-proof realm, comprising a housing that has a plurality of terminals at the controller end which are to be connected to at least one input/output module as well as terminals at the field device end which are to be connected to the field devices. The connection module of the invention is characterized in that the housing includes different resistors which are hard-wired to different terminals at the field device end and/or to terminals at the controller end in order to provide intrinsically safe pairs of terminals at the field device end which have different characteristic values.
