Function: FD0-VC-EX4.PA

The valve coupler for PROFIBUS PA connects up to four intrinsically safe low-power valves to the DCS via fieldbus. It is installed pre-wired in a field enclosure or directly outside, close to the valves in the hazardous area. The valve coupler drives four low-power auxiliary valves and gathers positioning information via pairs of inductive proximity switches.

The valve coupler communicates all data, configuration, and alarms via one fieldbus address to the DCS. It supports DCS integration through GSD file and FDT/DTM technology. Fieldbus powers the actors, sensors and the valve coupler itself. Additional power or wiring is not required.

The valve coupler supports the PROFIBUS PA profile for easy integration with summary diagnostics according to NAMUR recommendations, and detects lead breakage and short circuit conditions. It monitors and reports runtime and breakaway time during each operation and can conduct partial stroke tests.
