Bently Nevada 136294-01 — Transient Data Interface Module | 3500 Series Platform
Engineering Background
The Bently Nevada 3500 Series is the industry benchmark for continuous machinery protection and condition monitoring in rotating equipment applications. Deployed across power generation, oil & gas, petrochemical, and heavy industrial facilities worldwide, the 3500 rack-based architecture provides modular, scalable vibration and process monitoring with deterministic response times critical to turbomachinery protection.
Product Positioning
The 136294-01 is a Transient Data Interface (TDI) module within the 3500 Series ecosystem. It captures high-resolution transient waveform data from connected proximity probes and velocity/acceleration sensors during machine startup, shutdown, and trip events — providing the raw time-domain data essential for root-cause analysis, balancing studies, and OEM diagnostics. This module bridges real-time protection with post-event forensic capability, making it indispensable in any serious predictive maintenance program.

Proven Application Environments
- Power Generation: Steam turbines, gas turbines, and generator sets requiring continuous shaft vibration monitoring and transient capture during start/stop cycles.
- Oil & Gas: Compressor trains, expanders, and pipeline pumping stations where API 670 compliance mandates transient data recording for trip events.
- Petrochemical & Refining: Reactor charge pumps, cracked gas compressors, and critical rotating equipment with mandatory OEM data-logging requirements.
- Marine & Offshore: Propulsion turbines and auxiliary machinery where transient data supports classification society audits.
- Pulp & Paper / Heavy Industry: High-speed rolls and dryer section drives requiring waveform capture for balancing and alignment diagnostics.
Engineering Advantages
- High-Fidelity Waveform Capture: Records full time-domain vibration waveforms at machine-speed resolution — not just alarm states — enabling FFT, orbit, and Bode plot analysis in System 1 or third-party CMMS platforms.
- Seamless 3500 Integration: Plug-and-play within any 3500 rack; no additional signal conditioning or external DAQ hardware required.
- Event-Triggered & Continuous Modes: Configurable to capture on trip, alarm, or continuously — adapting to both protection and condition-monitoring workflows.
- Backward Compatibility: Fully compatible with legacy 3500 rack revisions and existing System 1 software installations, protecting prior capital investment.
- Reduced MTTR: Transient data captured at the moment of a trip dramatically reduces mean-time-to-repair by eliminating guesswork in root-cause analysis.
System Architecture & Signal Flow
The 136294-01 TDI module occupies a standard slot in the 3500 rack and communicates over the rack backplane with the 3500/22M TDI Communication Gateway module. Sensor signals enter via the I/O module terminal block, are conditioned and digitized within the TDI module, and buffered waveform records are transmitted to the gateway for Ethernet export to System 1 Evolution or equivalent historian. The module operates in parallel with the protection channel — transient data acquisition does not interrupt or degrade the real-time protection function.
Typical Signal Path: Proximity Probe → Proximitor/Seismic Transducer → 3500 I/O Module → 136294-01 TDI Module (waveform buffer) → 3500/22M Gateway → System 1 / Historian

Technical FAQ
Q: Is the 136294-01 compatible with the 3500/92 Communication Gateway?
A: No. The 136294-01 TDI module is designed to work with the 3500/22M TDI Communication Gateway. The 3500/92 is a separate Ethernet I/O module for a different data path. Confirm your gateway model before ordering.
Q: Can this module replace a standard 3500 monitor module?
A: No. The TDI module is a supplementary data-capture module, not a protection monitor. It must be used alongside standard 3500 monitor modules (e.g., 3500/40M, 3500/42M) which provide the actual protection relay outputs.
Q: What software is required to retrieve transient data?
A: Bently Nevada System 1 Evolution (v6.x or later) is the native platform. Third-party historians with OPC-DA/UA connectivity can also interface via the 3500/22M gateway.
Q: Do you provide the I/O module terminal block (136293-01)?
A: The terminal block is a separate line item. Please specify when ordering if you require the complete TDI assembly including the I/O module.
Q: What is the lead time for this part?
A: Typically 3–7 business days for in-stock units. Contact us for real-time availability confirmation.
