Embodiment Construction
[0018] figure 1 and figure 2 A plurality of juxtaposed electronic modules M of a programmable automation controller are shown.
[0019] The module comprises a housing 1 with side walls 1a, a front wall 1b and a metal rear wall 1c, which will also be referred to as the bottom of the module. It includes processor electronics on a printed circuit board in an enclosure.
[0020] The printed circuit is electrically connected to the interconnected printed circuit 2 at the base side via corresponding connectors 100 and 200 .
[0021] The interconnected printed circuit is carried by a support 3 , such as a metal panel, which is grounded. The interconnected printed circuit includes openings 20 .
[0022] The frame ground connection 4 connects the module to the panel from which it is insulated, through an opening 20 in the interconnection printed circuit. The insulator consists of an air gap or a layer of insulating material surrounding the opening.
[0023] The device 4 of the p...
