Bently Nevada 138607-01 Dual Transient Data Interface Module 3500 Series

Product Description

Overview

The Bently Nevada 138607-01 is a high-performance Dual Transient Data Interface (TDI) module designed for the 3500 Series machinery protection system. Installed in the rear of the 3500 rack, this module provides a direct interface for vibration sensors, enabling both static and dynamic data acquisition. Its internal termination design allows for straightforward wiring, eliminating the need for external terminal blocks, and supporting seamless integration with diagnostic software such as GE System 1.

Core Features

Data Acquisition and Processing

• High-speed Ethernet and USB connectivity for transferring large volumes of waveform and vibration data.

• Capable of capturing transient events including machine startups, coast-downs, and alarms.

• Simultaneous sampling across channels ensures precise phase correlation for orbit analysis and shaft centerline calculations.

Physical and Environmental Design

• Internal termination reduces installation complexity and conserves rack space.

• Hot-swappable module allows replacement without shutting down the 3500 rack.

• Rugged design tolerates harsh industrial environments, with high EMI and vibration resistance.

System Integration

• Compatible with the 3500/22M TDI system to maintain reliable sensor-to-network communication.

• Fully adheres to API 670 standards for machinery protection and condition monitoring.

• Supports RUN and PROGRAM modes for controlled configuration and operation, with a removable key to prevent unauthorized changes.

Technical Specifications

Applications

Ideal for predictive maintenance, the 138607-01 is critical for capturing diagnostic data that explains vibration trends and transient behaviors in rotating machinery. It complements standard 3500 modules that focus on trips and protection, enabling engineers to analyze and prevent equipment failures.

FAQ

What is the function of the 138607-01 module?
It serves as a high-speed interface for transient data collection between the 3500 rack and diagnostic software.

Can the module be replaced while the system is powered?
Yes, the hot-swappable design allows installation or replacement without downtime.

How do RUN and PROGRAM modes work?
RUN mode allows normal operation and prevents configuration changes. PROGRAM mode allows remote or local configuration, with a removable key for security.

Which sensors are compatible?
