Functional Features

1. Modular Architecture:
   • Slot Configuration:
     • Leftmost slots reserved for power supplies and rack interface modules (RIM).
     • Remaining slots accommodate a mix of monitoring modules (e.g., vibration, displacement, speed) and I/O modules .
   • Hot-Swap Capability: Modules can be replaced without powering down the system.
2. Centralized Data Management:
   • Real-Time Processing:
     • Aggregates data from up to 14 monitoring modules (e.g., 3500/42M for vibration, 3500/53 for speed) .
     • Supports waveform capture and trend analysis for predictive maintenance.
   • Alarm Handling:
     • Two-stage alarms (Alert/Danger) with configurable setpoints and relay outputs.
     • Fault logging with timestamped events (up to 200 records) .
3. System Integration:
   • Protocol Flexibility:
     • Integrates with PLCs and HMIs via industry-standard protocols.
     • Optional IEC 61131-3 PLC functionality for custom control logic .
   • Redundancy:
     • Dual power supplies and communication paths ensure fault tolerance.
4. User Interface:
   • Local HMI: Optional front-panel display for real-time status monitoring.
   • Remote Access: Web-based interface accessible via Ethernet for configuration and diagnostics .

Application Scenarios

1. Power Generation:
   • Steam/gas turbines, generators, and pumps in thermal/nuclear plants.
   • Example: Monitoring turbine shaft vibration and bearing temperature to prevent catastrophic failures .
2. Oil & Gas:
   • Compressors, centrifuges, and pipeline pumps in refineries and offshore platforms.
   • Example: Detecting impeller imbalance in a centrifugal compressor via 3500/42M modules .
3. Manufacturing:
   • Motors, gearboxes, and conveyor systems in automotive/chemical plants.
   • Example: Monitoring gear mesh frequency in a paper mill’s drive train for early wear detection .
4. Marine:
   • Shipboard engines, propeller shafts, and HVAC systems.
   • Example: Ensuring safe operation of a vessel’s main propulsion turbine through real-time speed and vibration analysis .
