Bently Nevada 123447-01 TDXnet Sampler Board | Machinery Protection Network Module | 3500 Series Platform
Engineering Background
The Bently Nevada 3500 Series is the industry benchmark for continuous online machinery protection, widely deployed in turbines, compressors, pumps, and generators across oil & gas, power generation, and petrochemical facilities. The TDXnet architecture enables high-speed, deterministic data acquisition across the protection rack, ensuring that transient vibration events are captured with full fidelity for both trip logic and condition monitoring analytics.
Product Positioning
The Bently Nevada 123447-01 TDXnet Sampler Board is a critical internal communication and signal-sampling module within the 3500 rack. It interfaces directly with transducer input modules to digitize and route raw vibration, position, and speed signals onto the TDXnet internal bus, making real-time data available to the rack monitor and external DCS/SCADA systems. Procurement engineers sourcing replacement or spare boards for 3500 Series racks will find this module essential for maintaining system integrity and avoiding unplanned downtime.

Proven Application Environments
- Gas turbine and steam turbine protection racks (3500/42M, 3500/44M, 3500/46M monitor cards)
- Centrifugal and reciprocating compressor monitoring systems
- Large rotating machinery in LNG, refinery, and power plant environments
- Replacement spare for existing 3500 Series racks requiring TDXnet board refresh
- System expansion projects adding new monitor modules to existing 3500 chassis
- Retrofit and upgrade programs migrating from legacy 3300 Series to 3500 architecture
Engineering Advantages
- Deterministic Sampling: TDXnet bus ensures synchronized, low-latency data transfer between input modules and the rack monitor, critical for accurate trip response.
- Drop-in Compatibility: Direct OEM replacement for 3500 Series racks — no firmware changes or reconfiguration required in most applications.
- High Signal Fidelity: Preserves full dynamic range of transducer signals (vibration, eccentricity, thrust, speed) before digitization.
- Rack-Level Redundancy Support: Compatible with 3500 redundant rack configurations for SIL-rated protection loops.
- Compact PCB Design: Minimal footprint within the 3500 chassis; does not consume a front-panel slot.
System Architecture & Signal Flow
Within the 3500 rack, transducer signals enter via front-panel input modules (e.g., 3500/42M Proximitor/Seismic Monitor). The 123447-01 TDXnet Sampler Board sits on the backplane and performs the following functions:
- Signal Acquisition: Receives analog transducer data from input module circuitry.
- Analog-to-Digital Conversion: Digitizes raw signals at high sample rates to preserve waveform integrity.
- TDXnet Bus Transmission: Packages digitized data and transmits via the TDXnet internal bus to the rack monitor module.
- Monitor Processing: The rack monitor applies alarm/trip logic, buffered waveform storage, and Modbus/OPC-UA output to DCS.
This architecture ensures that all signal processing decisions are made on fully digitized, time-stamped data — eliminating analog signal degradation across the backplane.
Sourcing & Quality Verification

Technical FAQ
Q: Is the 123447-01 compatible with all 3500 Series rack configurations?
A: The TDXnet Sampler Board is designed for use within the 3500 Series chassis. Compatibility depends on the specific monitor modules installed. Contact our engineering team with your rack configuration for confirmation.
Q: Can this board be used in a redundant 3500 rack?
A: Yes. The 3500 Series supports redundant rack configurations, and the TDXnet Sampler Board is compatible with these setups.
Q: What is the difference between new and refurbished units?
A: New units are unused OEM stock. Refurbished units have been professionally cleaned, inspected, and functionally tested to OEM specification. Both carry a 12-month warranty.
Q: Do you provide export documentation for international shipments?
A: Yes. We provide commercial invoices, packing lists, and certificates of origin. HS Code 8537.10 applies for most jurisdictions.
Q: What is the lead time for bulk orders?
A: Standard stock ships within 1–3 business days. For bulk quantities (>5 units), please contact us for availability and lead time confirmation.
