METSO D201435L

Series:​ Neles Series 2000 / ND9000 family compatible
Function / Working Principle:​
Receives a 4–20 mA DC analog setpoint signal from DCS/PLC and compares it with the actual valve stem position feedback (via internal cam/lever). A digital PWM-controlled piezo or nozzle-flapper pilot stage modulates supply air to the actuator, driving the valve to the commanded position in closed-loop control. Supports auto-calibration and adaptive gain tuning.

METSO D201832

Working Principle (D201832 Positioner):​
The positioner receives a 4–20 mA DC setpoint from the DCS/PLC and continuously compares it with real-time valve stem position sensed by a non-contact Hall-effect or potentiometric feedback linkage. A digital piezo pilot stage modulates supply air to the actuator in closed-loop control, driving the valve to the commanded position. Auto-calibration establishes the zero, span, and deadband; adaptive gain tuning compensates for actuator friction and seat load variation. HART 7 protocol is superimposed on the 4–20 mA loop for configuration, diagnostics, and partial-stroke testing.

METSO D201925

Function / Working Principle:​
Each of the 32 (or 16, depending on rack firmware revision) input channels accepts a 24 V DC wet contact or solid-state sensor signal from field devices — limit switches, proximity sensors, motor run status, ESD pushbutton contacts, etc. Optical isolation decouples field-side voltage transients from the system backplane. The module samples inputs at a configurable scan rate, applies software debounce filtering, and presents the binary state to the control engine for logic, interlocking, and alarm evaluation. LED indicators show per-channel ON/OFF status and module health. The module is hot-swappable in a live DNA rack.
