Bently Nevada 3500/22 288055-01+146031-01 Transient Data Interface Module

Product Introduction

The Bently Nevada 3500/22 288055-01+146031-01 Transient Data Interface Module (TDI) is a key communication and data processing unit in the 3500 Machinery Protection System.
It integrates the core functions of the 3500/20 Rack Interface Module (RIM) with advanced Ethernet or fiber-optic communication capabilities, enabling the transfer of both static and high-resolution transient waveform data to Bently Nevada’s System 1 or compatible monitoring software.

Installed exclusively in Rack Slot 1 (next to the power supply), this module continuously collects information from all monitoring and I/O modules in the rack. It processes machine health parameters, alarm conditions, and waveform data, transmitting them in real time without affecting the protective trip path.
When fitted with a Channel Enabling Disk, it allows full transient waveform capture before and after alarms, as well as speed-triggered event recording for in-depth diagnostics.

The combination 288055-01 main TDI board + 146031-01 I/O interface ensures compatibility with multiple network infrastructures and supports long-distance, noise-resistant fiber-optic data transmission.

Product Parameters

Product Applications

The 3500/22 288055-01+146031-01 TDI is widely used in industrial asset protection and predictive maintenance environments.
Key application areas include:

• Continuous machinery condition monitoring – Capturing steady-state parameters and transient vibration data.

• Event-based diagnostics – Recording machine behavior during alarms, trips, startups, and shutdowns.

• TMR (Triple Modular Redundancy) systems – Comparing redundant monitor outputs for fault isolation and voting.

• Integration with plant monitoring systems – Providing a data bridge to System 1 or DCS platforms.

• Remote configuration – Allowing secure software updates and parameter changes through RUN/PROGRAM mode selection.

• Alarm/event correlation – Linking waveform and static data for accurate root cause analysis.

Product Advantages

• Integrated dual-functionality – Combines RIM and communication processor into one module, reducing hardware complexity.

• Flexible networking options – Copper Ethernet or fiber-optic links for various plant layouts.

• Non-intrusive to protection logic – Data communication failures do not impact trip functions.

• High-resolution transient capture – Pre- and post-event waveform recording with enabling disk.

• Harsh-environment reliability – Wide temperature and humidity tolerance for industrial settings.

• Clear operational feedback – Multiple LED indicators and OK relay output for fast diagnostics.

• Optimized for M-series monitors – Full transient data capability with M-series rack modules.

FAQ

1. What is the difference between this TDI and a standard 3500/20 RIM?
   It integrates the RIM’s rack interface role with transient data capture and high-speed communication processing.

2. What is the purpose of the 146031-01 I/O interface?
   It provides the physical Ethernet or fiber-optic network connection and manages data transfer signals.

3. Does the TDI require an enabling disk to capture transient data?
   Yes, without it, only static data is collected and transmitted.

4. Can this module be used in TMR systems?
   Yes, it compares outputs from three redundant monitors to support fault voting.

5. Which rack slot does the TDI occupy?
   It must be installed in Slot 1, directly beside the rack power supply module.

6. Does a failure in the TDI affect machine protection?
   No, it is outside the protective trip path—protection remains active.

7. What data types can the TDI collect?
   Static parameters, alarm/event logs, and transient waveforms (when enabled).

8. What LED indicators are provided?
   OK, TX/RX, TM, and CONFIG OK, each signaling specific operational states.

9. How can rack configuration be controlled?
   Through a physical keylock switch for RUN or PROGRAM mode, enabling or blocking changes.

10. Does the TDI support speed-based triggering?
    Yes, it can initiate transient recording based on programmable speed windows.
