A connection scheme for a Programmable Logic Controller is taught. Briefly stated, a printed circuit board having a plurality of electrically conductive traces therein and a plurality of electrically conductive fingers associated with the conductive traces is disclosed. The pitch and size of the conductive fingers coincide with that of a PLC I/O connector. One or more of a plurality of interconnective devices may be connected to the printed circuit board thereby minimizing adverse thermal effects from adjacent thermocouple wires or providing for use of various interconnection devices or signal conditioning such as switches, displays, discrete devices and the like.
On présente ici un le schéma de câblage d'un contrôleur logique programmable (PLC). En bref, l'invention porte sur une carte de circuit imprimé comportant plusieurs lignes électroconductrices et plusieurs doigts électroconducteurs associés auxdites lignes. Le pas et la taille des doigts conducteurs coïncident avec ceux d'un connecteur d'E/S pour PLC. Un ou plusieurs des dispositifs d'interconnexion peuvent être raccordés au circuit imprimé pour réduire les effets thermiques néfastes des fils des thermocouples voisins, ou permettre d'utiliser différents dispositifs d'interconnexion ou de conditionnement de signaux tels que des commutateurs, des affichages, des dispositifs discrets, et analogues.
