Bently Nevada 133835-02 TC Isolated I/O Module

Product Overview

The Bently Nevada 133835-02 is a TC Isolated I/O Module engineered for reliable temperature monitoring within the 3500/61 machinery monitoring platform.
It enables stable thermocouple signal acquisition while protecting measurement integrity in electrically noisy industrial environments.
Moreover, the module integrates directly into the 3500 rack architecture, ensuring seamless compatibility with existing protection systems.
This design supports continuous condition monitoring for critical rotating equipment across demanding industrial applications.

Key Features and Functional Benefits

The module provides six independent temperature input channels, allowing comprehensive thermal coverage for complex machinery assemblies.
In addition, 250 Vdc channel-to-channel isolation effectively reduces ground loops and electrical interference risks.
Internal termination simplifies field wiring, therefore reducing installation time and minimizing common wiring errors.
Customizable alarm capabilities allow operators to react quickly to abnormal temperature conditions before damage escalates.
Furthermore, the rugged construction supports stable operation in harsh industrial environments with wide temperature variations.
