Abstract

A compact programmable logic controller provides a floating mounting of circuit cards carried by opposed terminal blocks of the industrial controller the latter only which are directly mounted to the housing. Positioning of the cards between opposed connector blocks prevents torsion on the cards resulting from unbalanced forces on the terminal blocks and provides an extremely rigid structure.
