Bently Nevada 133819-02 3500 Series RTD/TC Temperature I/O Module

Product Overview

The Bently Nevada 133819-02 serves as a specialized Temperature I/O Module with External Terminations for the 3500 Machinery Protection System. This module interfaces directly with the 3500/60 or 3500/61 Temperature Monitors to process signals from Resistance Temperature Detectors (RTD) and Thermocouples (TC). It acts as the physical connection point between field wiring and the rack backplane, ensuring precise thermal data acquisition for critical rotating machinery. We supply this component as 100% Brand New and original equipment to maintain the safety integrity of your monitoring network.

Part Number Breakdown

The 133819 series identifies the specific termination style and sensor compatibility for the 3500 temperature system:

• 133819: Base Series for Temperature I/O Modules.

• -02: Designates the External Termination version, designed for use with External Termination Blocks and mass-termination cables.

Technical Specifications

Engineering Advantages

• Simplified Field Wiring: The external termination (ET) design allows engineers to wire sensors to a remote terminal block rather than the back of the rack. This significantly reduces cable congestion in high-density cabinets and simplifies troubleshooting.

• Superior Signal Isolation: High-quality shielding within the 133819-02 protects low-voltage RTD and TC signals from electromagnetic interference (EMI). This prevents "signal bounce" and false temperature alarms in environments with heavy motor activity.

• Rapid Module Replacement: Because the field wiring stays connected to the external block, technicians can swap the I/O module in seconds without disturbing the field cables, minimizing "Not OK" status duration during maintenance.

• Environmental Resilience: The module features industrial-grade components that withstand the high temperatures and vibrations found in localized turbine or compressor control rooms.

FAQs

• Can I use the 133819-02 for direct wiring without an external block?

  No. The -02 version requires an External Termination Block and a 3500 mass-termination cable. If you require direct wiring to the back of the rack, you must select the Internal Termination (IT) version of the I/O module.

• Does this module support both RTDs and Thermocouples simultaneously?

  Yes, the 3500/60 and 3500/61 monitors are programmable. The 133819-02 provides the physical path for either sensor type, provided you configure the monitor software to match the specific sensor connected to each channel.

• How do I ensure 100% signal accuracy?

  Always use the correct extension wire for Thermocouples and ensure the 133819-02 is securely seated in the rack. The module includes precision cold-junction compensation circuitry to maintain accuracy across fluctuating ambient temperatures.

• Is this module hot-swappable?

  Yes, you can remove and install the 133819-02 while the rack is powered. However, the associated monitor will enter a "Not OK" state and will not provide protection for the machinery during the swap.
