Metso D201832

Product Name:​ Integrated Power Supply and Processor Module / DCS Module according to configuration
Product Introduction:​ D201832 appears in Metso automation documentation as either an Integrated Power Supply and Processor unit for Valmet/Metso DNA racks or as another DCS/automation module according to project code. For power-processor use, it supplies regulated internal bus power and supports rack processing functions.

Detailed content

Technical Specifications:
  • Input power: 24 VDC nominal, extended range according to IPSP variant configuration
  • Output power: regulated internal bus voltages for DNA I/O and controller sections
  • Mounting: dedicated slot in Metso/Valmet DNA or ACN I/O rack
  • Protection: overvoltage, overcurrent and reverse-polarity protection according to power variant
  • Status: front LEDs for input, output and fault conditions
Functional Features:
  • Conversion of cabinet 24 VDC into regulated rack logic power
  • Backplane noise filtering and surge suppression
  • Redundant operation support with second power-processor module according to rack design
  • Hot-swap support when redundancy and system rules permit
Material Composition:
  • Enclosure: industrial metal or reinforced electronic module housing according to rack variant
  • PCB: FR4 power and control boards with high-temperature components
  • Power devices: DC-DC converters, filters and protection semiconductors
  • Connectors: plated backplane and power contacts
Structural Characteristics:
  • Dedicated power-processor module form factor
  • Front diagnostic LED panel
  • Rear backplane power and communication interface
  • Internal galvanic isolation between input and output sections
Working Principle:​ The module receives bulk 24 VDC from the cabinet power bus. Internal filtering and DC-DC conversion produce regulated voltages for the backplane, I/O modules and controller electronics. Diagnostic circuits monitor input voltage, output load and internal faults, then report status through front LEDs and rack communication.
Installation Requirements:​ Install in the assigned power-processor slot. Verify 24 VDC cabinet supply, polarity and rack grounding. For redundant configuration, install the second unit and confirm load-sharing before energizing I/O.
Usage Precautions:​ Do not remove the only healthy power-processor module while the rack is live. Confirm redundant Output OK status before hot-swap. Keep rack ventilation paths clear. Replace with the identical D201832 variant approved for the rack firmware.
