The attached schematics illustrate examples of the DVC6200 SIS in different operational modes, including point-to-point mode or multi-drop mode. The DVC6200 SIS can receive command signals from either a DCS (Basic Process Control System, BPCS) or a logic solver (Safety Instrumented System, SIS). These are fundamental schematics designed to detail the connections between the control system and the user interface. Diagrams labeled "PST Only" specifically show the use of a DVC6200 SIS with a reverse acting relay (relay B).
These drawings are for reference ONLY. It is possible to have many different combinations or permutations of such schematics.
