Bently Nevada 3500/22 138607-01+146031-01 Transient Data Interface Module

Product Introduction

The Bently Nevada 3500/22 138607-01+146031-01 Transient Data Interface (TDI) Module is a core component of the Bently Nevada 3500 Machinery Protection System. It serves as both the communication gateway and configuration interface for the rack, replacing the functions of the 3500/20 Rack Interface Module with enhanced transient data capabilities. The TDI module not only manages all communication between the rack and external systems via Ethernet but also collects and transmits high-resolution transient data for detailed machinery diagnostics.

Designed for use in demanding industrial environments such as power plants, oil refineries, petrochemical complexes, and heavy manufacturing facilities, this module integrates continuous protection with condition monitoring, enabling operators to make fast, informed decisions. Its high-speed data acquisition, combined with compatibility with System 1® software, allows for comprehensive event analysis and long-term machinery health trending.

Product Parameters

Product Applications

The Bently Nevada 3500/22 TDI Module is widely deployed in industries where machinery reliability is mission-critical. Typical applications include:

• Turbomachinery Monitoring – Steam, gas, and hydro turbines for vibration and event diagnostics.

• Rotating Equipment – Compressors, pumps, motors, and generators requiring transient event analysis.

• Condition-Based Maintenance (CBM) – Integrates continuous condition monitoring for predictive maintenance strategies.

• Industrial Process Reliability – Ensures uptime in petrochemical, power generation, and marine propulsion systems.

• Event Capture and Post-Event Analysis – Records transient vibration data for fault investigation.

Product Advantages

• Dual Functionality – Combines rack communication and transient data capture in a single module.

• High-Resolution Data Acquisition – Captures short-lived events with precision, aiding in early fault detection.

• Seamless System Integration – Works natively with Bently Nevada 3500 racks and System 1® software.

• Reduced Hardware Requirements – Eliminates the need for a separate Rack Interface Module.

• Enhanced Diagnostic Capabilities – Provides both static and dynamic machinery health data.

• Robust Industrial Design – Built to operate reliably in harsh environmental conditions.

FAQ

1. What is the main difference between the 3500/22 TDI and the older 3500/20 Rack Interface Module?
   The 3500/22 TDI integrates all 3500/20 functions and adds high-speed transient data acquisition for advanced diagnostics.

2. Can the TDI module operate without System 1® software?
   Yes, it can provide protection functions without System 1®, but full transient data analysis requires System 1®.

3. How does the TDI module handle transient data storage?
   It stores high-resolution waveform data locally before transmitting it to a connected host system for analysis.

4. Is the 3500/22 compatible with all 3500 rack configurations?
   Yes, it is compatible with standard 3500 racks and can be installed in the designated slot for rack interface modules.

5. Does the TDI require a dedicated Ethernet connection?
   A dedicated connection is recommended for maximum performance and reliable data transfer.

6. What sampling rate is used for transient event capture?
   The exact rate depends on the channel type, but it is high enough to capture rapid changes in vibration signals.

7. Can the module be hot-swapped during operation?
   No, it must be powered down before removal or replacement to prevent system disruption.

8. How does the TDI contribute to machinery protection?
   It processes and transmits real-time condition data to the rack’s protection logic, ensuring fast response to faults.

9. Is firmware upgradable in the field?
   Yes, firmware can be updated via Ethernet to add features or improve performance.

10. What protocols are supported for external communication?
    Primarily Ethernet TCP/IP, with support for Modbus/TCP for integration with control systems.
