3. Key Technical Specifications

4. Product Introduction (Anti-Template)

The Bently Nevada 3500/22M Transient Data Interface (TDI) serves as the communication and data collection hub for a 3500 monitoring rack. It combines the functions of a traditional Rack Interface Module (RIM) with the ability to collect both steady-state and transient waveform data from the monitors in the rack.

The module always occupies Slot 1 (next to the power supplies) and is required in every 3500 rack. It continuously gathers data from compatible M-series monitors and transmits it over Ethernet to System 1 machinery management software. Static data collection is standard; dynamic/transient data capture is enabled with an optional Channel Enabling Disk. Because the TDI sits outside the critical protection path, its operation or failure does not affect the basic alarming and shutdown functions of the monitor modules. A TMR version is available for triple-modular-redundant configurations.

5. QC, Procurement & Logistics SOP

1. Inbound Verification – Confirm full model (3500/22M), I/O module type (copper or fiber), any revision or agency approvals, and connector condition. Photograph all labels.
2. Functional Testing – Install in a 3500 rack, apply power, verify OK and communication LEDs, and confirm Ethernet link where possible.
3. QA & Packaging – Protect the backplane connector and Ethernet ports, clean the module, and pack in anti-static protective packaging.
4. Global Logistics & Export Compliance – Classify under the correct HS code for industrial monitoring modules. Packaging must protect against electrostatic discharge and mechanical shock; export documentation is prepared to minimize customs delays.

6. Technical Pitfalls & Integration Warnings

Slot Location – The TDI must be installed in Slot 1. Installing it elsewhere prevents proper rack communication.

I/O Module Matching – Select the correct I/O module (10/100Base-TX or 100Base-FX) for the network infrastructure. Mismatched media prevents System 1 connectivity.

Channel Enabling Disk – Transient/dynamic data collection requires the optional enabling disk. Without it, only static data is available.

TMR Systems – Standard and TMR versions of the TDI are not interchangeable. Use the TMR TDI in TMR racks.

7. Frequently Asked Questions (FAQ)

What is the realistic global lead time for a verified 3500/22M?
As a core 3500 system module, availability is generally good through surplus channels. Typical lead time after verification is 5–15 business days plus standard shipping.

What is the function of the 3500/22M?
It is the Transient Data Interface that provides rack communication and collects steady-state and transient data for System 1 software.

Where does it install in the rack?
Always in Slot 1, next to the power supplies.

Does every 3500 rack need one?
Yes. Every 3500 rack requires either a 3500/22M TDI or a 3500/20 RIM.

What network options are available?
10/100Base-TX copper Ethernet or 100Base-FX fiber-optic Ethernet.

Is the 3500/22M still supported?
Yes. It remains a standard component of the 3500 platform and is widely available for both new and existing systems.

What should be confirmed before ordering a replacement?
Exact model (3500/22M), I/O module type (copper or fiber), standard vs TMR version, and compatibility with the existing System 1 software version.
