It captures high-resolution transient data during machine startup, coastdown, and transient events, storing it for analysis in diagnostic software such as System 1 or 3500 System Diagnostics. The TDI module is essential for understanding machine behavior during critical operating phases. The 128275-01 interfaces with the 3500 rack via the backplane, collecting data from monitoring modules (vibration, position, speed) at high sampling rates. It communicates with external systems via Ethernet for data retrieval and analysis. This unit is new surplus, factory-sealed in original Bently Nevada packaging. 3500 components remain critical for turbomachinery protection; contact us for current stock and firm pricing. Frequently Asked Questions (FAQ) Q: What is the 3500/22M TDI module used for? A: The BENTLY 128275-01 (3500/22M) captures transient data—high-speed recordings of machine vibration, position, and speed during startup, coastdown, and transient events. Unlike steady-state monitoring, transient data reveals: Critical speeds (resonances) Thermal response Rubs and looseness during startup Bearing behavior during speed changes This data is essential for engineers analyzing machine health and diagnosing problems. The 128275-01 stores this data for retrieval by diagnostic software. Q: What’s the difference between 128275-01 and the standard 3500/22M? A: The 128275-01 IS the 3500/22M TDI module. The part number 128275-01 is Bently Nevada’s specific ordering code for this module. The “01” suffix may indicate: Standard configuration Specific firmware version Hardware revision Always match the exact part number from your existing system. In 3500 racks, the TDI module is critical for diagnostics—using the wrong revision may cause communication or data compatibility issues. Q: Does the 128275-01 require a Rack Interface Module (RIM)? A: Yes. The BENTLY 128275-01 works in conjunction with the Rack Interface Module (RIM, typically 3500/20 or 3500/22) in the 3500 rack. The RIM handles basic rack communication; the TDI adds transient capture capability. You need both for full functionality. The TDI module mounts in a dedicated slot (usually slot 2 or as configured) and communicates with the RIM via the backplane. Q: What kind of data does the TDI capture? A: The 128275-01 captures: Startup/coastdown data: Vibration amplitude and phase vs. speed Transient events: Sudden changes in vibration or position Time waveforms: Raw vibration signals Spectrum data: Frequency analysis during events Orbit plots: Shaft centerline motion This data is stored in the module’s memory and can be retrieved via Ethernet using Bently Nevada software (System 1, 3500 System Diagnostics). It’s invaluable for rotordynamic analysis. Q: How do I retrieve data from the 128275-01? A: Data is retrieved via: Ethernet connection to the TDI module (using its IP address) Bently Nevada software (System 1, 3500 System Diagnostics, or older tools) Modbus (limited, for basic values) The 128275-01 has its own Ethernet port for direct connection. In typical installations, it’s connected to a plant network, and engineers access it from workstations running diagnostic software. You can also connect directly for troubleshooting. Q: What do the front panel LEDs indicate on the 128275-01? A: The BENTLY 128275-01 has status LEDs: OK (green): Module operational, self-test passed TX/RX (yellow): Ethernet communication activity FAULT (red): Internal fault or configuration error ACT (yellow): Transient data capture in progress If OK is green and FAULT off, module is healthy. If FAULT lights, check rack configuration and communication settings. During transient capture, ACT may flash. Q: Can the 128275-01 be hot-swapped? A: No. The 128275-01 is not hot-swappable. To replace it: Power down the 3500 rack (or at least remove power from the slot) Remove old module Install new 128275-01 Restore power Configure IP address and settings via software Attempting hot-swap can damage the module, backplane, or both. Schedule a controlled outage for replacement. In critical machinery, ensure monitoring is covered by redundant systems if available. Q: What’s the typical failure mode for TDI modules? A: In my experience: Ethernet port damage—surges on network cables (most common) Memory corruption—rare, but can happen during power loss Power supply section aging—internal regulators fail Firmware corruption—requires reload The BENTLY 128275-01 is generally reliable, but Ethernet connections in industrial plants are vulnerable. If the module powers up but won’t communicate, the Ethernet PHY may be damaged. If it won’t boot, internal power supply may have failed. Keep sprites for critical machinery. Q: What software do I need to configure the 128275-01? A: You need Bently Nevada’s 3500 System Configuration software to set up the TDI module initially. This configures: IP address and network settings Data capture triggers (speed, time, event) Channel mapping Communication protocols Once configured, data retrieval uses System 1 or 3500 System Diagnostics. If you’re replacing a failed 128275-01, you’ll need the original configuration file or must reconfigure from scratch. Always keep backups. Q: Can the 128275-01 communicate with third-party systems? A: Yes, within limits. The 128275-01 supports: Modbus TCP for basic data access OPC via System 1 gateway EtherNet/IP (depending on firmware) For full transient data analysis, you need Bently Nevada software. Third-party systems can read some data via Modbus, but not the high-resolution transient waveforms. For integration, plan on using System 1 as a gateway or purchase additional licenses. Q: What’s the difference between 128275-01 and 128275-02? A: The suffix (-01 vs -02) typically indicates: Different firmware version Hardware revision Specific feature set (e.g., additional communication protocols) The 128275-01 is the standard TDI module. 128275-02 may have enhanced memory, faster processor, or updated features. Always match the exact part number from your existing system. In critical machinery monitoring, using the wrong revision can cause data compatibility issues. Verify with Bently Nevada’s documentation. Q: How much transient data can the 128275-01 store? A: The BENTLY 128275-01 has onboard memory for multiple transient events—typically enough for several startups or coastdowns. Exact capacity depends on: Number of channels configured Sampling rate Event duration In practice, it stores enough data for most diagnostic needs. For long-term archiving, data is uploaded to System 1 or other databases. The TDI acts as a buffer, not a long-term historian. Q: Does the 128275-01 require a separate power supply? A: No. The 128275-01 is powered from the 3500 rack backplane. It draws power from the rack’s power supply(s). Ensure your rack’s power budget includes the TDI module. In redundant power configurations, the TDI is covered by both supplies.
