Abstract
A controller base unit for a DIN-standard installation wherein a molded base is provided with an internal chassis for support and a contour that permits the direct and releasable attachment of the unit to a DIN rail via a plurality of hooks that are simultaneously moveable between an engaged and non-engaged position. The base is provided with a recess in a planar face thereof for accommodating a printed circuit board and has fixed tabs along the periphery of the recess. The circuit board has cut-outs that mate with the tabs for insertion of the board into the recess and is slidable laterally into a position where the tabs secure the board against the surface of the recess and a screw or the like can secure the board against further lateral movement. The board has at both ends thereof a pair of connectors that are connectable with either end of a separate similarly designed board via a cable. With this board design, the length of cable connections between boards arranged horizontally, vertically, side-by-side, etc. can be minimized.
