Description
The Bently Nevada 133819-02 is a 6-channel RTD/TC Non-Isolated I/O module designed for use with the 3500/61 Temperature Monitor within the 3500 Machinery Protection System. This module features internal terminations and provides critical temperature monitoring capabilities by conditioning inputs from Resistance Temperature Detectors (RTDs) and Thermocouples (TCs). It compares these inputs against user-programmable alarm setpoints to ensure the integrity and safety of rotating machinery. Unlike the 3500/60 variant, the 3500/61 series (including this 133819-02 module) provides recorder outputs for each of its six channels.
Features
- 6-channel high-density temperature monitoring
- Integrated recorder outputs for each channel
- Supports both RTD (2, 3, 4-wire) and Thermocouple (J, K, T, E) inputs
- Configurable alarm setpoints via 3500 Rack Configuration Software
- Hot-swappable functionality for maintenance without system shutdown
- Real-time hardware self-testing for diagnostic reliability
Applications
- Turbines: Monitoring bearing and casing temperatures for gas, steam, and hydro turbines.
- Compressors: Tracking critical temperatures in centrifugal, axial, and reciprocating compressors.
- Generators: Stator and bearing heat monitoring for large-scale power generation.
- Motors and Pumps: Overheating protection for continuous-operation industrial motors and pumps.
- Gearboxes: Oil and bearing temperature monitoring to detect early signs of wear or friction.

Installation Guidelines
- Ensure the 3500 rack power is disconnected before installing or removing the I/O module.
- Handle the module using proper ESD (Electrostatic Discharge) precautions to prevent damage to internal circuitry.
- Verify that the I/O module matches the configuration of the 3500/61 monitor module installed in the rack.
- Ensure all internal wiring is securely terminated according to the site-specific loop diagrams.
- Maintain adequate ventilation around the 3500 rack to prevent overheating of the I/O components.
- Route sensor signal cables away from high-voltage or high-EMI sources to minimize signal noise.
FAQ
What is the Bently Nevada 133819-02?
The Bently Nevada 133819-02 is a 6-channel RTD/TC Non-Isolated I/O Module with internal terminations, designed for the 3500/61 temperature monitoring system to measure resistance temperature detectors and thermocouples.
What is the function of the 133819-02 module?
It is used for temperature monitoring in 3500 series racks. It conditions sensor inputs and compares them to user-defined alarm setpoints to trigger alerts or shutdowns.
Does this module include recorder outputs?
Yes, the 133819-02 (3500/61) includes recorder outputs for each of its six channels, which allows for external signal processing or data logging.
What is the difference between 133819-02 and 133819-01?
Both are 6-channel I/O modules, but they are not interchangeable. The 133819-02 is specific to the 3500/61 monitor which supports recorder output functionality.
