Description
Bently 3500 22-01-02-00
Technical Specifications
- Module Type: TMR Transient Data Interface
- Configuration: 02 (TMR)
- Network Interface: 10/100 Base-TX Ethernet
- Slot Requirement: Slot 1
Functional Features
- Monitor Channel Comparison: Continuously compares the outputs of three redundant monitors in real-time.
- Voting Logic: If one monitor’s output deviates from the other two beyond a configured percentage, the TDI flags it as faulty and logs a system event.
- Enhanced Reliability: Ensures that transient data captured and transmitted is highly accurate and free from single-point failures.
Application Scenarios
Mandatory for highly critical machinery protection systems, such as large steam turbines, nuclear auxiliary pumps, and compressors where false trips or missed trips are unacceptable.
Performance Parameters
- Operating Temperature: -30°C to +65°C
- Storage Temperature: -40°C to +85°C
- Humidity: 95% non-condensing
- Voting Response Time: Real-time comparison
Material Composition
High-reliability components designed to meet stringent safety integrity levels (SIL) for TMR architectures.
Structural Characteristics
Full-height module with front-panel LEDs indicating TMR voting status, communication health, and fault conditions.
Working Principle
Receives data from three redundant monitors, executes a 2-out-of-3 voting algorithm, and only transmits validated, accurate transient data to the host system.
Installation Requirements
Must be installed in Slot 1. Requires a fully configured TMR rack with three redundant monitors and TMR relay modules.
Usage Notes
Standard TDI modules cannot be used in TMR racks. The TMR TDI must be properly configured via the 3500 Rack Configuration Software to enable the monitor comparison voting logic.
