ABSTRACT:
A control station for use individually or as an element of a distributed process control system has an improved high frequency isolation and grounding system incorporating a "Chomeric" conductive foil tape on both the cabinet front and back walls as well as on the doors and a V-shaped "Chomeric" conductive gasket placed between the cabinet wall and the door in the area of the conductive tape to insure proper sealing of the door and opening to eliminate all RFI (radio frequency interference) problems and meet European standards for RFI cabinet emmisions. This cabinet also has a grounding system comprising a large area swing clip for removing the door as well as a hybrid grounding circuit to eliminate ground potential differences due to geological variations found in different parts of the landscape since the signals reaching the cabinet may originate at remote locations up to a mile or more from the cabinet. The circuit accomplishes this by grounding the DC signals at only one end while the AC signals are grounded at both ends
