Bently Nevada 125840-02 Proximitor/Seismic I/O Module | External Terminations

Description

1. Product Overview

The Bently Nevada 125840-02 is a 4-channel Proximitor/Seismic I/O Module specifically designed to work with the 3500/42M Proximitor Seismic Monitor. This module serves as the critical interface between field transducers and the 3500 rack.

Unlike the internal termination version, the 125840-02 is engineered for External Terminations. It allows field wiring to be connected to an External Termination Block (ETB) rather than directly to the back of the rack. This configuration is preferred in large-scale industrial setups to simplify cable management and enhance system maintainability.

Key Applications:

• High-Density Wiring: Ideal for projects using centralized termination panels.
• Vibration Analysis: Provides signal conditioning for radial vibration, thrust position, and casing vibration.
• Asset Protection: Critical for monitoring turbines, compressors, and large motors in the oil, gas, and power sectors.

7. FAQ

Q: What is the main difference between 125840-02 and 125840-01?

The 125840-01 features Internal Terminations, where field wires are connected directly to terminal blocks on the module. The 125840-02 uses External Terminations, meaning it connects via a cable to a separate terminal block (ETB) mounted elsewhere. Choose the -02 version if your cabinet uses a centralized wiring design for easier maintenance.

Q: Does this module include the External Termination Block (ETB) and cables?

No, the 125840-02 refers specifically to the I/O module that fits into the 3500 rack. The interface cables and the ETB are separate components. Please contact us if you need the full assembly for a new installation.

Q: Is the 125840-02 interchangeable with other I/O modules?

It is only interchangeable with other 3500/42M I/O modules, but you must ensure your wiring matches (Internal vs. External). You cannot use it with a 3500/32 or 3500/25 main module.
