Key Technical Specifications

Bently Nevada identifies 288055-01 as the Standard Transient Data Interface Module with USB cable. The TDI combines functions associated with the 3500/20 Rack Interface Module with communication-processor data collection capability. It continuously collects steady-state and transient data from compatible M-Series monitors and transfers that information through Ethernet.

BENTLY-350022M-288055-01 Cable

The module is installed in Slot 1, directly next to the 3500 rack power supplies. Static data collection is standard, while dynamic and high-resolution waveform collection depends on the appropriate channel-enabling configuration.

Product Introduction (Anti-Template)

When a 3500 rack needs to move machinery condition data from its monitoring modules to a host diagnostic system, the 3500/22M TDI acts as the rack-level data interface. The 288055-01 version is the standard TDI, equipped for Ethernet communication and USB-based configuration. It works with M-Series monitors such as the 3500/40M and 3500/42M to collect steady-state values and transient waveform information.

One important distinction: the TDI is not part of the critical automatic machinery protection path. A failure can interrupt data collection or communication without necessarily disabling the normal protective function of the individual monitor modules. Every 3500 rack requiring this interface uses a TDI or RIM in Slot 1.

QC, Procurement & Logistics SOP

1. Inbound Verification
   Verify the complete identification: 3500/22M / 288055-01. Check the front-panel label, hardware revision, serial number, connector condition, key switch, rack-address switches, and USB configuration port. The 288055-01 designation corresponds to the standard TDI spare module.
2. Live Rig Testing
   On a compatible 3500 rack, verify module initialization, OK status, rack address, communication with M-Series monitors, Ethernet data transfer, and USB configuration access. Where the application uses transient collection, test the corresponding waveform acquisition function rather than relying solely on the front-panel LEDs.
3. QA & Anti-Static Packaging
   Handle the module under ESD precautions. Protect the backplane connector and front-panel communication ports with suitable cushioning. The module should remain immobilized inside the carton during transportation.
4. Global Logistics & Export Compliance
   Export documentation should identify the product as a Bently Nevada 3500/22M 288055-01 Standard Transient Data Interface Module. HS classification should be reviewed according to the actual product function and destination customs requirements. For urgent machinery-monitoring repairs, air freight is normally the practical option; sea freight can be considered for planned consolidated shipments.

Technical Pitfalls & Integration Warnings

1. TDI Type / I/O Module Mismatch
   The 3500/22M ordering structure includes separate fields for TDI type, I/O module type, and agency approval. The standard 288055-01 spare should therefore be matched against the existing rack configuration rather than treated as interchangeable with every 3500/22M variant.
2. RIM-to-TDI Upgrade Error
   This is a serious installation point. Bently Nevada documentation specifically warns that leaving the old 3500/20 RIM I/O in the rack while installing a new TDI can damage the TDI. The documented upgrade sequence is: remove RIM, remove RIM I/O, install TDI I/O, then install TDI.
3. Dynamic Data Configuration
   Static data collection is standard, but dynamic and high-resolution transient collection requires the appropriate channel-enabling configuration. If a customer expects waveform capture immediately after replacing the module, check the existing enabling arrangement first.
4. ESD and Rack Installation
   Do not handle the PCB or backplane interface casually during replacement. Isolate the equipment according to the approved maintenance procedure, use ESD protection, and verify the rack slot before insertion. The TDI belongs in Slot 1 next to the power supplies.

Frequently Asked Questions (FAQ)

Q1: “What exactly does the 3500/22M 288055-01 do?”

It is the Transient Data Interface for a Bently Nevada 3500 rack. It collects steady-state and transient information from compatible M-Series monitor modules and transfers that data to host monitoring and configuration software through the rack’s communication interface.

Q2: Is 288055-01 the standard version?

Yes. Bently Nevada documentation lists 288055-01 as the Standard Transient Data Interface Module with USB cable. The TMR version is separately identified as 288055-02.

Q3: “Where does the 3500/22M go in the rack?”

It occupies Slot 1, immediately next to the power supplies. This is an important installation requirement, not simply a preferred position.

Q4: Can the 3500/22M be hot-swapped?

Do not assume live replacement is acceptable simply because the 3500 system uses modular hardware. Follow the approved maintenance procedure for the specific rack configuration. If the module is being installed as part of a RIM-to-TDI upgrade, the documented removal and insertion sequence must be followed to avoid damaging the TDI.

Q5: “Does 288055-01 provide transient waveform collection?”

Yes, but the available transient-data capacity depends on the channel-enabling configuration. Static data capture is standard; dynamic and high-resolution transient collection requires the appropriate enabling configuration. The total steady-state and transient point allocation can be up to 672 points, subject to the documented configuration limits.

Q6: Can I replace a 3500/20 RIM directly with a 3500/22M?

Not as a simple one-for-one insertion. The TDI upgrade requires the appropriate TDI I/O module and a specific removal/install sequence. Bently Nevada explicitly warns that leaving the RIM I/O installed when inserting the TDI can damage the new module.

Q7: “What information should I send before ordering?”

Please provide:

• Existing 3500/22M nameplate photo
• Complete part number
• Hardware revision
• Existing I/O module part number
• Agency approval option, if applicable
• 3500 rack configuration
• M-Series monitor models installed
• Whether transient waveform capture is required
• Quantity required
• Destination country
• Required delivery date

For this part, 288055-01 alone is not always enough for engineering verification. If possible, send a photo of both the front label and the rear I/O assembly. That makes it much easier to confirm the exact TDI configuration before shipment.
