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.
