Description
METSO 2440 D100532
Technical Specifications: 24 VDC power supply from system backplane; adopt Metso proprietary I/O bus protocol; rack plug‑in installation mode; operating temperature range 0 ℃ to +60 ℃; LED indicators for system running and bus activity; protection class IP20.
Functional Features: Realize bus signal routing inside control rack; maintain time synchronization between CPU and I/O modules; bus signal conditioning and filtering; hardware communication fault detection; upload bus fault alarm to host monitoring system; guarantee real‑time data interaction of whole rack I/O equipment.
Application Scenarios: Metso Damatic XDi system main control rack; thermal power plant auxiliary equipment DCS cabinet; pulp and paper mill process control cabinet; chemical plant small‑scale unit control cabinet.
Performance Parameters: Low bus signal transmission delay; strong anti‑interference performance for internal bus; high data transmission reliability; adapt to 7×24 hours long‑term continuous operation.
Material Composition: Fiberglass epoxy multilayer circuit board; bus signal processing chip; signal matching components; gold‑plated backplane connector; metal front panel; circuit board with three‑proof conformal coating.
Structural Features: Standard rack plug‑in card structure; front panel carries LED indicator group for power, running and bus fault; rear gold‑plated connector connects with system backplane; internal circuit separates bus receiving unit and sending unit; mechanical locking buckle prevents module loosening caused by vibration.
Working Principle: D100532 receives instruction data sent by main CPU through backplane bus, routes and distributes data to corresponding I/O module slot. At the same time it collects feedback data uploaded by each I/O module, aggregates and transmits data to main controller. Module monitors bus signal quality all the time, outputs fault alarm once bus communication failure occurs.
Installation Requirements: Insert module into specified dedicated slot of Damatic XDi rack. Guarantee backplane connector fully engaged. Cabinet protective grounding terminal shall realize reliable connection. Keep enough surrounding space for ventilation and heat dissipation. Do not occupy other functional module slots.
Precautions for Use: Cut off rack backplane power supply before plugging or removing module. Wear anti‑static wrist strap when touching circuit board. Do not apply external power supply directly to module. Inspect backplane connector contact status regularly. Prevent dust accumulation on module surface. Avoid cabinet internal condensation.
