Metso PDP401

Product Introduction:​
The Metso PDP401 is a microprocessor-based industrial automation device used either as a smart valve positioner for pneumatic control valves in process plants, or as a compact Distributed Processing Unit (DPU) in Metso DNA / Valmet DNA distributed control systems. It converts a 4–20 mA analog control signal into a precise pneumatic output to position the valve, or performs real-time I/O scanning, logic, and communication in a DCS node.
