Product Description
The Bently Nevada 3500/22M Transient Data Interface (TDI) is the primary communication gateway for the 3500 Machinery Protection System. Unlike standard interface modules, the 288055-01 (22M version) possesses the advanced capability to collect “transient” data, such as waveform snapshots during machine startup and coastdown. It acts as the bridge between the 3500 rack and Bently Nevada’s System 1 software, providing high-resolution diagnostic information while maintaining the rack’s primary function of machinery protection and trip logic.
Application Fields
This module is essential for critical rotating machinery monitoring, including steam and gas turbines, centrifugal compressors, and large industrial pumps. It is extensively used in power generation, oil and gas processing, and heavy manufacturing sectors. The TDI is specifically required when an operator needs both real-time machinery protection and deep-dive vibration analysis for predictive maintenance and fault diagnosis.

Operational Precautions
-
Ensure the TDI is installed in the slot immediately adjacent to the rack power supplies (typically Slot 1).
-
Use high-quality shielded Ethernet cables to prevent data packet loss or corruption in high-EMI environments.
-
Do not attempt to update the module firmware while the machinery protection system is actively controlling critical trip logic.
-
Regularly verify the “OK” LED status on the front panel to ensure the module is actively communicating with the backplane.
