Bently 3500/22 288055-01N

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

Brand: Bently Nevada
Series: 3500 Machinery Protection System
Product Type: Transient Data Interface (TDI) Module


Product Overview

The Bently Nevada 3500/22 288055-01N Transient Data Interface (TDI) is the primary communication and data-acquisition module for the 3500 Machinery Protection System. Installed in Slot 1 of the 3500 rack, this module connects the rack to monitoring and diagnostic software such as System 1, enabling advanced machine condition monitoring, transient data capture, and predictive maintenance.

The TDI combines the functions of a Rack Interface Module (RIM) and a communication processor, making it the central gateway between field sensors, monitoring modules, and plant networks.


Key Features

Central Communication Gateway

The 3500/22 module enables high-speed communication between the 3500 monitoring rack and external systems.

Interfaces include:

  • 10/100Base-T Ethernet connectivity
  • USB port for local configuration and maintenance
  • Support for plant networks and condition monitoring platforms

This ensures seamless integration with control rooms and asset management systems.


Transient and Static Data Acquisition

The TDI continuously collects and transmits both steady-state data and dynamic waveform data, allowing engineers to monitor machine health in real time.

It supports data from:

  • Proximity probes
  • Accelerometers
  • Velocity sensors
  • Position and speed sensors

This enables complete visibility into machine behavior.


Event-Triggered Recording

The module supports advanced trigger modes for capturing critical events:

  • Alarm and trip triggers
  • Time-based waveform capture
  • Startup and shutdown recording
  • Threshold and manual triggers

This makes it possible to analyze faults precisely when they occur.


High Reliability for Industrial Environments

Designed for continuous operation in demanding environments, the module offers:

  • Industrial temperature tolerance
  • Robust rack-mounted design
  • Continuous online monitoring capability

Ideal for mission-critical rotating equipment.

Main Functions in the 3500 System

The 3500/22 TDI performs several critical roles:

  1. Collects data from monitoring modules
  2. Transfers data to diagnostic software
  3. Stores transient waveform events
  4. Provides rack configuration and setup
  5. Enables remote monitoring and troubleshooting

Without the TDI module, the 3500 rack cannot communicate with external systems.


Typical Applications

The Bently Nevada 3500/22 288055-01N is widely used for protecting and monitoring:

  • Steam and gas turbines
  • Compressors
  • Pumps and motors
  • Generators
  • Fans and blowers
  • Oil & gas rotating equipment
  • Power plant machinery

It is a key component in predictive maintenance programs across heavy industry.


Difference Between 288055-01N and 138607-01

Model Difference
288055-01N Standard package including USB cable
138607-01 Base version without USB cable

Both versions provide identical performance and functionality.


Why Choose the 3500/22 TDI Module

  • Essential for 3500 rack communication
  • Enables advanced vibration and waveform analysis
  • Supports predictive maintenance strategies
  • Improves equipment reliability and uptime
  • Trusted worldwide in critical industrial applications
