Description
METSO D200533
Technical Specifications: Power supplied by rack backplane 24 VDC; adopt Metso proprietary XD bus protocol; rack plug‑in installation; operating temperature range ‑20 ℃‑+70 ℃; LED indicators for power, bus running and communication fault; weight 0.63 kg; protection class IP20.
Functional Features: Realize bus signal routing inside control rack; maintain time synchronization for all modules within rack; bus signal filtering and impedance matching; hardware communication fault diagnosis; fault status upload to host monitoring system; guarantee high‑speed data exchange between controller and I/O modules.
Application Scenarios: Damatic XD system main control rack cabinet; pulp and paper mill production line DCS cabinet; thermal power plant auxiliary system control cabinet; chemical plant small‑scale unit automation cabinet.
Performance Parameters: Low bus transmission delay; strong anti‑interference performance for internal bus signal; high data transmission reliability; adapt to long‑term continuous operation in industrial cabinet environment.
Material Composition: Fiberglass epoxy multilayer PCB; bus protocol processing chip; signal matching and surge suppression components; gold‑plated backplane connector; metal front panel; three‑proof conformal coating on circuit‑board surface.
Structural Features: Rack plug‑in modular card structure; front panel reserved LED indicator area; rear gold‑plated edge connector connects with system backplane; internal receiving circuit and sending circuit are physically separated; mechanical locking buckle equipped on front panel.
Working Principle: D200533 receives instruction data sent by DPU controller through backplane bus, distributes data to corresponding I/O module slot. Meanwhile it collects feedback data uploaded by each I/O module, aggregates data and transmits back to main controller. Module monitors bus signal quality all the time. When communication abnormality occurs, fault indicator activates and alarm message uploads to upper monitoring workstation.
Installation Requirements: Install D200533 into specified dedicated slot of Damatic XD rack. Ensure backplane connector fully inserted. Cabinet protective grounding terminal connects reliably. Keep adequate ventilation clearance around module for heat dissipation.
Precautions for Use: Cut off rack backplane power supply before plug‑in and pull‑out operation. Wear anti‑static wrist strap when touching circuit‑board components. Do not apply external power supply directly to module. Inspect connector contact status regularly. Prevent dust accumulation on module surface.
