Bently Nevada 3500/20 (125744-02) Rack Interface Module (RIM)
1. Primary Functions
Central Communication Hub:
Acts as the main interface between the 3500 rack and external systems (DCS, SCADA, System 1®), enabling data configuration and retrieval.
Routes signals (e.g., vibration, temperature) from monitoring modules (e.g., 3500/25, 3500/40) to external processors like TDXnet and DDIX.
System Coordination:
Supports real-time data transmission for machinery protection and condition monitoring.
Provides status LEDs (OK, TX/RX, CONFIG OK) for operational diagnostics.
Configuration & Redundancy:
Features a key-lock switch for local/remote programming (RUN/PROGRAM modes).
Enables hot-swappable replacement and dual-module redundancy for fail-safe operation.
2. Technical Specifications
Installation: Must occupy Slot 1 (adjacent to power supplies) in the 3500/05 rack.
Communication: RS-232/RS-422 (38.4k baud) and internal modem (14.4k baud).
3. Applications
Machinery Protection: Coordinates alarms/shutdowns for critical equipment (turbines, compressors).
Condition Monitoring: Integrates with System 1® for predictive maintenance.
