製品紹介
The Bently Nevada 3500/22 146031-02 Transient Data Interface Module (TDI) is a key communication module for the 3500 Machinery Protection System. It merges the functions / the 3500/20 Rack Interface Module (RIM) with an integrated communication processor, enabling high-speed transfer / both static and transient data to external s/tware platforms such as System 1. Installed in Slot 1 / the rack, the TDI collects real-time information from all monitoring modules, processes event triggers, and sends detailed waveform and status data over Ethernet or fiber-optic links. With an optional Channel Enabling Disk, it can capture detailed pre- and post-event transient waveforms for advanced diagnostics.

Product Applications
The 3500/22 146031-02 TDI is widely deployed in critical rotating machinery protection and condition monitoring systems. Its key applications include:
-
Data acquisition for machinery diagnostics: Capturing and transferring both static parameters and high-resolution transient waveforms.
-
Integration with predictive maintenance s/tware: Seamless connection with Bently Nevada System 1 for real-time analysis.
-
Transient event analysis: Monitoring startups, shutdowns, load changes, and trips.
-
Redundancy and fault comparison: In Triple Modular Redundant (TMR) configurations, comparing monitor outputs for fault detection.
-
Remote rack configuration and monitoring: Securely allowing or locking configuration changes via RUN/PROGRAM modes.
Product Advantages
-
Two-in-one integration – Combines RIM and communication processor in a single module, reducing hardware count.
-
Non-critical to protection path – Failure does not disable protective trip functions, ensuring operational safety.
-
Multiple network options – サポートs both copper Ethernet and fiber-optic connections for flexible plant integration.
-
Advanced transient capture – Optional enabling disk allows high-resolution waveform recording before and after alarms.
-
Environmental robustness – Designed for industrial conditions with wide temperature and humidity tolerances.
-
Clear status feedback – LED indicators and OK relay provide immediate health and communication status.
FAQ
-
What is the primary role / the TDI in the 3500 system?
It serves as both the rack interface and the data communications processor, collecting and transmitting monitoring data to external systems. -
Can the TDI operate without an enabling disk?
Yes, but without it, transient waveform capture is not available—only static data is transmitted. -
How does the TDI handle communication failures?
Loss / communication is indicated by LED status changes and can be logged in the system for troubleshooting, without affecting protection. -
What slot in the rack is the TDI installed in?
It must be installed in Slot 1, directly next to the power supply module. -
Does the TDI process data from all rack modules?
Yes, it gathers information from all installed monitors and I/O modules. -
Can the TDI be used in TMR configurations?
Yes, it compares data from three redundant monitors to identify and isolate faults. -
What communication protocols does the TDI support?
It uses proprietary Bently Nevada protocols over Ethernet or fiber, compatible with System 1 s/tware. -
How is rack configuration controlled through the TDI?
A physical keylock switch sets RUN or PROGRAM mode, allowing or preventing configuration changes. -
What types / data can be collected?
Static measurements, alarm statuses, and transient waveform data (when enabled). -
Does the TDI require specific monitor module versions?
Yes, it works best with M-series monitors for full transient capture capability.
