Product Overview

The Bently Nevada 3500/40 (126615-01) is a specialized 4-channel Proximitor I/O module designed for the 3500 Series Machinery Protection System. This specific variant enables External Termination (ET), allowing maintenance teams to decouple field wiring from the 3500 rack. By routing signals through a remote DIN-rail mounted terminal block, this module simplifies high-density cable management in complex control cabinets. We supply this unit as 100% New and Original, providing the critical interface needed for high-accuracy radial vibration, thrust position, and eccentricity measurements.

Engineering Advantages

High-Density Wiring Management: The external termination architecture eliminates the struggle of landing heavy field cables directly onto the back of the 3500 rack. Instead, you land field wires on a remote ET Block, connecting to the 126615-01 via a single multi-conductor cable.
Rapid Module Replacement: Because field wiring stays connected to the external terminal block, you can swap out the I/O module in seconds without re-terminating individual sensor wires. This drastically reduces Mean Time to Repair (MTTR).
Versatile Monitoring Modes: This single I/O type supports multiple measurement configurations. Software settings determine whether the channels monitor Radial Vibration for shaft motion, Thrust Position for bearing protection, or Differential Expansion for thermal growth tracking.
Signal Integrity in Remote RIEs: Optimized for Remote Instrumentation Enclosures (RIE), the 126615-01 maintains high signal-to-noise ratios even when consolidating multiple transducer signals from distant machinery trains.

Monitoring Capabilities

The 126615-01 processes inputs for the following critical machine states:

Radial Vibration: Detects dynamic shaft motion to identify imbalance or misalignment.
Thrust Position: Protects against catastrophic axial contact in turbines and compressors.
Eccentricity: Measures shaft bow during slow-roll startup sequences.
Differential Expansion: Monitors the relative growth between the machine casing and the rotor.

FAQs

What is the main benefit of the 126615-01 over the internal termination version?

The 126615-01 utilizes External Termination (ET). This allows you to organize field wiring on DIN-rail blocks outside of the rack's immediate footprint, which is essential for cabinets where space is limited or where frequent maintenance requires easy access to wiring without disturbing the rack.

Which terminal blocks are compatible with the 126615-01?

This module requires Bently Nevada External Termination Blocks (typically the 125808-05 or similar). You must also use the correct multi-conductor "ET Cable" to bridge the distance between the module and the terminal block.

Can I use this I/O module with 3300 XL NSv probes?

Yes, provided the front-mounted 3500/40 monitor card is configured for the NSv scale factor. The 126615-01 handles the raw signal pass-through from the Proximitor® sensor to the monitor regardless of the specific probe diameter.

Does this I/O module include the front-mounted 3500/40 monitor card?

No. Part number 126615-01 refers specifically to the rear I/O module. In a complete system, you must pair this with a 3500/40 or 3500/40M monitor card installed in the front of the rack.
