Description

Bently‑Nevada 3500/22‑01‑01‑00 Transient Data Interface Assembly (288055‑01 Main Board + 146031‑01 Ethernet I/O Module)

Product Description

The 3500/22‑01‑01‑00 (TDI, Transient Data Interface) is the rack‑level core communication gateway for Bently‑Nevada 3500 machinery‑protection rack本特利. The complete assembly includes front‑side processor main board 288055‑01 and rear‑mount Ethernet I/O daughter‑board 146031‑01 (10Base‑T /100Base‑TX copper Ethernet).

Replacing the older 3500/20 Rack Interface Module (RIM), this TDI module occupies the dedicated slot‑1 position adjacent to rack power supply. It integrates rack management, backplane communication, steady‑state measurement readout and high‑speed transient dynamic‑data acquisition functions. It transfers orbit waveform, spectrum, start‑up / coast‑down transient data to System 1® condition‑monitoring & diagnostic software, and supports connection with 3500 Rack Configuration Software via front‑panel USB‑B portBaker Hugh…. It is mandatory for every 3500‑M‑series rack; it does not participate in machinery protection voting logic and will not affect protection channel operation upon communication‑side fault. OEM manufacturing is discontinued; supplied only as aftermarket replacement spare part for legacy 3500‑M‑series installations本特利.

Technical Specifications

Key Features & Benefits

1. All‑in‑one rack gateway: Combines traditional RIM rack‑management function plus high‑speed transient‑data acquisition; one module fulfills rack administration, configuration access and machinery diagnostic‑data output, eliminates separate TDX‑net hardware本特利.
2. Rich dynamic diagnostic‑data output: Captures orbit plots, vector, spectrum and transient startup/coast‑down data; configurable trigger conditions by speed‑band, delta‑RPM or time interval; internal buffer retains historical pre‑trigger data for fault‑event playback.
3. Standard copper‑Ethernet interface: 146031‑01 rear I/O provides auto‑sensing 10/100 Mbit twisted‑pair Ethernet for connection to System 1 host workstation. Front‑panel USB‑B enables local laptop configuration without network setupBaker Hugh….
4. System health relay output: Front‑panel OK‑relay provides remote rack‑health status signal for DCS/SCADA, indicating TDI operational and rack‑backplane integrity status.
5. Non‑interference with protection logic: Communication‑path faults will not impact hardwired alarm‑relay and protection‑trip logic of monitor channels, ensuring machinery‑protection reliability.
6. Drop‑in backward‑compatibility: Works with all 3500‑M‑series monitor boards, power‑supply assemblies and legacy rack firmware; direct spare‑part swap‑out for existing 3500‑M‑series racks. Rear I/O daughter‑board supports hot‑swap; front CPU board requires slot power removal for replacement.

Application Fields

• Machinery‑protection racks for steam turbines, gas turbines, centrifugal / axial compressors in power‑generation, petrochemical and oil‑gas facilities, deployed together with System 1® predictive‑diagnostic platform for vibration spectrum, orbit and transient startup‑coast‑down analysis.
• 3500‑M‑series rack central gateway for rack configuration, health‑status reporting and uploading dynamic machinery‑diagnostic data to supervisory host‑system.
• Spare‑part replacement and retrofit for legacy 3500‑M‑series sites originally equipped with 3500/22‑01‑01‑00 TDI assemblies.

• 3500/40M / 3500/42M / 3500/50 / 3500/60 series: M‑series monitor modules supplying measurement and transient‑source data to TDI
• System 1® Condition‑Monitoring Software: Host diagnostic platform receiving TDI transient data
• 3500 Rack Configuration Software: For rack‑parameter setup via front‑panel USB‑B
• 146032‑01: Alternative rear I/O (100Base‑FX fiber‑optic Ethernet) for long‑distance noisy‑EMI‑environment application

Installation and Maintenance

Installation

1. Insert complete 3500/22‑01‑01‑00 assembly (288055‑01 main board pre‑mated with 146031‑01 rear I/O) into fixed Slot 1, the first slot adjacent to rack power‑supply module.
2. Wire OK‑relay dry‑contact terminals to external DCS/SCADA status‑input circuit according to site‑safety‑drawings.
3. Connect twisted‑pair Ethernet cable to RJ45 port of 146031‑01 rear‑I/O; establish network link toward System 1 host workstation. Local configuration may use front‑panel USB‑B with configuration‑laptop.
4. Complete rack‑wide configuration via 3500 Rack Configuration Software; enable transient‑data‑collection parameters (speed trigger, frequency‑span, orbit‑channel pairing).
5. Apply rack power; verify front‑panel OK‑LED is illuminated; check rack event‑log for TDI‑health, backplane‑communication and Ethernet‑link‑status diagnostics.

Important Note: 3500/22‑01‑00 must be installed in Slot 1. Only rear‑side 146031‑01 I/O supports hot‑swap. Front‑side 288055‑01 CPU board must be inserted / removed with slot power disabled. TDI is communication‑gateway only; it does not perform machinery‑protection voting.

Maintenance

1. Perform periodic visual inspection: check rear‑I/O Ethernet‑port, OK‑relay terminals, front‑panel USB‑B connector for dust and loose connections.
2. Regularly review rack‑event‑log for TDI‑fault, backplane‑communication‑fault or Ethernet‑link‑down alarms. Troubleshoot network infrastructure upon communication drop‑out.
3. For rear‑I/O communication‑fault: hot‑swap 146031‑01 while rack remains powered‑on; verify Ethernet‑link and data‑upload status after replacement.
4. For main‑board fault: power‑down Slot 1 before removing 288055‑01 CPU board; reassemble with matched rear‑I/O module, download rack‑configuration and verify full‑function recovery.
5. Avoid mechanical shock and conductive contamination during module‑handling. Refer to official Bently‑Nevada document 161581 (3500/22M TDI Datasheet) for full installation constraints and troubleshooting guidance.
