Bently‑Nevada 3500/22M‑01‑02‑00 Transient Data Interface (TDI) Assembly (288055‑01 + 146031‑01)
Product Description
The 3500/22M‑01‑02‑00 is a mandatory rack‑level Transient Data Interface (TDI) gateway module for Bently‑Nevada 3500‑M‑series machinery‑protection rack. The full assembly consists of front TDI main control board 288055‑01 and rear fiber‑optic Ethernet I/O daughter‑board 146031‑01.
This module replaces the legacy 3500/20 RIM unit. It acts as central rack controller, configuration gateway and high‑speed transient data collector. It communicates with all M‑series monitor modules over rack backplane bus, gathers steady‑state measurement values, alarm status, time‑stamped event logs and high‑resolution dynamic waveform data. The rear 146031‑01 provides 100Base‑FX fiber‑optic Ethernet for long‑distance, high‑noise‑immunity connection to System 1 condition‑monitoring software and 3500 Rack Configuration SoftwareNexAuto Te….
Every 3500‑M rack must be fitted with exactly one 3500/22M module. Important: TDI is not part of the machinery protection voting path; loss of TDI communication will not disable monitor alarm and trip functions. OEM production discontinued; supplied only as aftermarket replacement spare for turbomachinery TSI systems.

Key Features & Benefits
- All‑in‑one rack controller gateway: Combines legacy RIM rack‑management function and high‑speed transient data processor in single module, reduces total slot consumption and hardware count inside rack.
- Fiber‑optic Ethernet communication: 100Base‑FX optical interface eliminates ground‑loop interference, supports long‑distance host connection for heavy‑EMI industrial plant environments.
- Integrated static & transient data acquisition: Collects real‑time process values, alarm status, plus high‑resolution dynamic waveform data for machine startup, shutdown and trip event post‑fault analysis. Transient waveform capture requires optional software license key.
- Local event‑log storage: Stores large quantity of time‑stamped system alarms, monitor faults and diagnostic events locally on‑board, available for download even when host software is offline.
- Hardware‑based rack health relay: Front‑panel OK relay provides hard‑contact rack‑system‑healthy signal to external annunciator or DCS, independent of network communication status.
- Backward‑compatible maintainable architecture: Works exclusively with 3500‑M‑series monitor modules (3500/40M, 3500/42M, 3500/50, 3500/60, 3500/70M, 3500/92 etc.). Rear‑side 146031‑01 supports hot‑swap; front‑side 288055‑01 main‑board must be replaced with slot power disabled. TDI failure will not impact monitor protection trip logic.
Application Fields
‑ Power‑generation, petrochemical and natural‑gas facilities: mandatory rack gateway for 3500‑M TSI racks monitoring steam turbines, gas turbines, centrifugal compressors and reciprocating compressors. Delivers machinery data to System 1 predictive‑diagnostic platform, supports rack configuration upload/download and event‑log retrieval.‑ Rotating‑machinery protection projects requiring fiber‑optic communication for heavy‑electromagnetic‑interference field sites, complying with API‑670 standard.‑ Spare‑part replacement and system retrofit for legacy 3500‑M racks originally equipped with fiber‑optic variant 3500/22M‑01‑02‑00 transient‑data‑interface assembly.

Installation and Maintenance
Installation
- Assemble front main‑board 288055‑01 and matched rear I/O board 146031‑01 as one unit; insert assembly into the dedicated RIM slot (adjacent to 3500/15 power‑supply half‑height slots). One rack requires exactly one 3500/22M module.
- Set rack unique address via DIP switches on front panel; connect multi‑mode fiber cable to SC connector on rear‑side 146031‑01 I/O board.
- Connect laptop via front‑panel USB‑B port, launch 3500 Rack Configuration Software, complete rack configuration download; apply transient‑data‑capture license key if dynamic waveform function is required.
- Power‑up rack; verify front‑panel OK LED stays illuminated; check rack event‑log for TDI hardware or backplane‑communication faults; confirm online connection status with System 1 host software.
Important Note: Only rear‑side 146031‑01 supports hot‑swap under rack powered‑on. Front‑side 288055‑01 main‑board must be installed or removed with corresponding slot power disabled. TDI fault does not affect machinery protection trip outputs. Fiber optic interface cannot be mixed with copper‑twisted‑pair I/O rear‑board without full assembly replacement.
Maintenance
- Periodically inspect rear‑side fiber connector cleanliness, front‑panel LED status and OK‑relay external wiring during routine site inspection.
- Regularly download and review TDI stored time‑stamped event‑log for system‑level troubleshooting.
- For rear‑I/O communication fault: hot‑swap 146031‑01 while rack remains powered‑on; verify fiber‑optic Ethernet communication after replacement.
- For main‑processor hardware fault: power‑down dedicated RIM slot before extracting 288055‑01 main‑board; reassemble with matched rear I/O module, re‑download rack configuration and validate full‑function recovery.
- Avoid mechanical shock and conductive contamination during module‑handling. Refer to Bently‑Nevada official document Doc‑161581 (3500/22M TDI Datasheet & Operation Manual) for complete installation constraints and detailed troubleshooting guidance.
