Bently Nevada 3500/20 125760-01 Data Manager I/O Module
1. Overview
The 3500/20 125760-01 is a Rack Interface Module (RIM) that serves as the central communication hub for the Bently Nevada 3500 Machinery Protection System.
It manages data flow between monitoring modules, external systems, and diagnostic software.
2. Key Functions & Features
System Coordination & Data Management:
Acts as the primary interface between the 3500 rack and external devices (e.g., DCS, SCADA, System 1® software).
Processes and routes vibration, temperature, and Keyphasor® signals from monitoring modules (e.g., 3500/25, 3500/40).
Configuration & Diagnostics:
Supports local/remote programming via a key-lock switch (RUN/PROGRAM modes).
Provides status LEDs (e.g., CONFIG OK, TM) for real-time system health monitoring.
Redundancy & Reliability:
Enables hot-swappable module replacement without disrupting system operation.
Compatible with dual power supplies (3500/15) for fail-safe operation.
Integration Capabilities:
Interfaces with 3500/22M Transient Data Interface (TDI) for advanced diagnostics.
Supports 63 unique rack addresses for multi-rack installations.
3. Applications
Machinery Protection: Coordinates alarms and shutdowns for turbines, compressors, and pumps.
Condition Monitoring: Streamlines data transfer to System 1® for predictive maintenance.
Industrial Automation: Links to DCS/PLC systems via relay/output modules (e.g., 3500/44).
