Bently Nevada 3500/20 Rack Interface Module (RIM)
1. Core Functions
Central Communication Hub:
Acts as the primary interface between the 3500 rack and external systems (e.g., DCS, SCADA, System 1®), enabling data exchange and remote monitoring.
Manages configuration and retrieval of machinery data via proprietary protocols.
System Coordination:
Processes signals from monitoring modules (e.g., vibration, temperature) and routes them to external processors (e.g., TDXnet, TDIX, DDIX).
Supports real-time data transmission to integrated control systems.
Configuration & Diagnostics:
Features a key-lock switch for local/remote programming (RUN/PROGRAM modes).
Provides status LEDs (e.g., CONFIG OK, TM) for system health monitoring.
Redundancy & Reliability:
Allows hot-swappable replacement and dual-module redundancy for fail-safe operation.
Compatible with dual power supplies (3500/15) for continuous operation.
2. Technical Specifications
Communication Protocols: RS-232/RS-422 (38.4k baud), internal modem (14.4k baud).
Installation: Must occupy Slot 1 (adjacent to power supplies) in the 3500/05 rack.
Power Consumption: 4.75W.
3. Applications
Machinery Protection: Coordinates alarms/shutdowns for turbines, compressors, and pumps.
Condition Monitoring: Integrates with System 1® for predictive maintenance.
Industrial Automation: Links to DCS/PLC systems via relay modules (e.g., 3500/44).
