New Bently Nevada 3500/22-01-01-00 100Base-TX Interface

Product Overview

The Bently Nevada 3500/22-01-01-00 functions as the primary communication and data acquisition gateway for the 3500 Machinery Protection System. Known as the Transient Data Interface (TDI), it bridges the gap between the 3500 monitoring rack and System 1* software. This module collects steady-state and transient dynamic data (such as waveforms) while providing critical Keyphasor* phase reference signals for synchronous vibration analysis. We supply this module as 100% Brand New and Original (Made in USA), ensuring high-speed data throughput and API 670-compliant phase tracking for your most critical rotating assets.

Technical Specifications

The 3500/22-01-01-00 handles high-bandwidth data transfers while conditioning precise timing pulses.

Engineering Advantages

• High-Resolution Data Capture: The TDI captures high-resolution "snapshot" data during machinery transients (startups and shutdowns). This allows engineers to analyze Bode and Polar plots to identify critical speeds, structural resonances, and rotor damping characteristics.

• Integrated Keyphasor Functionality: This module acts as the rack's Keyphasor source. It converts raw sensor pulses into precise timing markers, enabling synchronous sampling across all vibration channels in the rack for accurate vector analysis.

• Enhanced Ethernet Throughput: The 146031-01 I/O module provides a 100Base-TX Ethernet interface. This high-speed connection ensures that large waveform files transfer quickly to the System 1* server without bottlenecking the machinery protection functions.

• Robust Signal Conditioning: The 3500/22-01-01-00 applies industrial-grade filtering to Keyphasor inputs. It eliminates "false triggers" caused by electrical noise or gear tooth imperfections, providing a rock-steady phase reference for machine diagnostics.

• Streamlined Configuration: Featuring a front-access USB port (via the 288055-01 module), the TDI allows technicians to configure the entire 3500 rack locally without needing a network connection, simplifying commissioning and troubleshooting.

FAQs

• What is the difference between a standard 3500/25 and this 3500/22?

  The 3500/22 (TDI) replaces the older 3500/20 (RIM) and 3500/25 (Keyphasor) modules by combining their functions. It provides both the communication gateway and the phase reference signals in a single, more powerful interface.

• Can I use this module to monitor rotor speed?

  Yes. The 3500/22 processes Keyphasor signals to determine instantaneous rotational speed, which it shares across the 3500 backplane for use by other monitors and for display on the rack's front panel.

• Does the module support redundant Ethernet connections?

  While the 3500/22-01-01-00 typically utilizes a single Ethernet port for data transfer, it maintains full compatibility with redundant 3500 power supplies to ensure the communication link stays active during a power fault.

• Is the USB cable included with the module?

  Yes. The 288055-01 component includes the standard USB cable required for local rack configuration and maintenance.
