Executing continuous machinery protection functions within the 3500 rack system, the Bently Nevada 176449-01+125680-01 pairs a four-channel 3500/40M Proximitor Monitor with a 125680-01 internal termination I/O module. This combination processes high-frequency inputs from proximity transducers to provide precise measurements of radial vibration, thrust position, eccentricity, and differential expansion. By embedding terminal connections directly onto the 125680-01 I/O card, the assembly eliminates the need for external terminal blocks, reducing cabinet footprint and simplifying complex field wiring in demanding environments.

| Manufacturer | Bently Nevada |
| Monitor Module Part Number | 176449-01 (3500/40M) |
| I/O Module Part Number | 125680-01 (Internal Terminations) |
| System Compatibility | Bently Nevada 3500 Monitoring System |
| Number of Channels | 4 independent channels |
| Input Transducer Support | Proximitor Transducers (including 3300 XL series) |
| Signal Range | -24 VDC nominal loop supply; standard proximity probe outputs |
| Termination Type | Internal Terminal Strips (Screw-clamp) |
| Operating Temperature | -30 to +65 degC |
| Country of Origin | United States of America (USA) |
| Shipping Weight | 10.0 kg (including packaging and modules) |
| Terminal Block Label | Signal Assignment / Function |
|---|---|
| Ch 1 PROX / COM / SIG | Channel 1 Transducer Power, Ground, and Signal Return |
| Ch 2 PROX / COM / SIG | Channel 2 Transducer Power, Ground, and Signal Return |
| Ch 3 PROX / COM / SIG | Channel 3 Transducer Power, Ground, and Signal Return |
| Ch 4 PROX / COM / SIG | Channel 4 Transducer Power, Ground, and Signal Return |
| SHLD Terminals | Common instrumentation shield ground points (isolated from chassis) |
The 125680-01 I/O module utilizes screw-type internal terminals, making it mechanically incompatible with racks configured for external termination blocks (which utilize different cable assemblies and the 125680-02 external termination I/O). When hot-swapping or replacing older 3500/40 units, ensure the firmware revision of the 176449-01 matches the version programmed in your 3500 Rack Configuration software to prevent slot mismatch errors and module inhibit states.
Because internal termination cables attach directly to the 125680-01 card at the rear of the rack, direct mechanical stress is placed on the card's backplane connector. Implement robust wire-tie and cable tray strain reliefs within the panel to decouple external weight. Ensure the total load on the -24 VDC transducer power loop does not exceed the system specifications when using non-standard extension cables or custom-length proximity sensor runs.
Always ground the sensor cable shields at the dedicated SHLD terminals on the 125680-01 module. Never ground the shield at both ends, as this introduces ground loops that corrupt low-voltage proximity measurements with 50/60 Hz industrial noise. Prior to active commissioning, verify that the configured transducer scale factor (e.g., 7.87 V/mm / 200 mV/mil) aligns precisely with the calibrated scale factor of the installed Proximitor sensor.
