ABSTRACT:
By providing an input/output panel housing which is readily connectible to adjacent housings and which cooperates with up to four removable input/output modules, a completely expandable, modularized input/output panel construction is achieved. Each housing accommodates up to four "plug-in" input/output modules, and is constructed so that the wiring from the equipment being controlled is connected directly to fixed terminals and need not be removed when the input/output modules are removed or replaced. Since each housing is readily connectible to adjacent housings, the input/output panel board construction of this invention is completely flexible and readily expandable to meet any desired operational needs.
