Abstract
A rack mountable weld controller for use as a plug in card within a rack of a programmable logical controller (PLC) system. All signals between the PLC and the weld controller are through the backplane of the rack in which the weld controller is installed. In this manner, the large number of signals which are needed to operate the weld controller may be passed through the backplane rather than over a set of cables connecting the weld controller to an input card and output card which are themselves plugged into a backplane slot.
