Metso D200175 Analog Input Field Module for ND9000 Digital Valve Positioner

Product Description

D200175 is Metso dedicated signal acquisition board matched with ND9000 intelligent valve positioner.

It collects 4–20mA analog control signals and converts to digital data for valve stroke closed-loop control, equipped with D-Sub communication port and rack backplane connector. PCB with conformal coating, plug-in rack design, supports on-site valve calibration and fault diagnosis, widely used as replacement spare for petrochemical, pulp and paper flow control cabinets.

Key Features

Specialized signal conversion board for Metso ND9000 valve positioner, ensures precise valve stroke positioning control.

High-precision analog signal sampling filters field interference to eliminate valve jitter under unstable input signals.

D-Sub debug port supports on-site parameter tuning, stroke auto-calibration and hardware fault reading.

Standard 64-pin backplane connector realizes stable data interaction with positioner main control unit.

Compact plug-in structure enables quick disassembly and one-to-one direct replacement without complex wiring.

Full circuit galvanic isolation resists EMI interference from pumps, compressors and heavy field equipment.

Anti-corrosion conformal coated PCB adapts to humid, dusty chemical plant field environments.

Rugged anti-vibration layout, stable 24/7 continuous flow control operation for pipeline regulating valves.
