Product Overview
The Bently Nevada 126615-01 serves as the primary 4-channel I/O module for the 3500/40M Proximitor Monitor system. This module interfaces directly with proximity transducers, conditioning raw eddy current signals into precise vibration and position measurements. We supply this unit as 100% Brand New and Original, providing the critical hardware interface required for high-accuracy monitoring of turbomachinery, compressors, and pumps within the 3500 rack architecture.

Engineering Advantages
-
High-Density Monitoring: The 126615-01 processes four independent channels within a single rear rack slot. This maximizes rack space efficiency, allowing for comprehensive monitoring of multiple bearing points or both X and Y radial vibration on two separate bearings.
-
Precise Transducer Powering: The module provides a regulated -24 Vdc power supply to each connected Proximitor® sensor. This ensures stable sensor operation and maintains the accuracy of the 200 mV/mil scale factor essential for API 670 machinery protection standards.
-
Advanced Signal Conditioning: Internal circuitry filters and conditions raw signals before passing them to the 3500/40M main processor. This active conditioning rejects common-mode noise and electromagnetic interference (EMI) often present in high-power motor environments.
-
Rugged Environmental Resilience: Designed for continuous duty in industrial plants, the module withstands temperatures up to 65°C and 95% non-condensing humidity. Its robust internal architecture prevents signal drift during thermal cycling.
FAQs
1. Does the 126615-01 support internal or external termination?
The 126615-01 is an Internal Termination (IT) module. Field wiring from the proximity probes connects directly to the screw terminals located on the rear of the I/O card. You do not need an external termination block for this configuration.
2. Can I use this I/O module with 3300 XL 8mm and 5mm probes?
Yes. The 126615-01 works seamlessly with both 3300 XL 5mm and 8mm proximity transducer systems. Ensure your 3500/40M main module is configured correctly via software to match the specific scale factor of your probes.
3. What is the difference between the 126615-01 and the 126615-02?
The -01 version typically refers to the standard Internal Termination configuration. The -02 or other suffixes may indicate different agency approvals or special termination styles. Always verify your specific 3500 rack backplane requirements before ordering.
4. How does the 126615-01 handle a sensor failure?
The module continuously monitors the "Not OK" status of each channel. If a probe wire breaks or the sensor fails, the I/O module detects the invalid voltage and triggers a "Not OK" status to the 3500/40M monitor, preventing false alarms.
