Product Information:

The Bently Nevada 128229-01 is a dedicated backend hardware component, referred to as a proximity/seismic input/output (I/O) module with internal termination. It operates within the Bently Nevada 3500 Series machinery protection system and must be physically paired with a 3500/42M proximity seismic monitoring master processing card (e.g., part number 176449-02) in a front-mounted slot.

This module provides real-time, continuous, and automatic over-limit alarms and interlocking protection for rotating machinery, and supports hot-swapping and 100Base-FX fiber optic Ethernet bus communication, ensuring high-density, deterministic condition monitoring in harsh industrial environments such as petrochemical plants and power plants.

Overview Manuals Principle Primary Applications

Features:

  • Prox/Seismic I/O Module
  • Proximitor Seismic Monitor is a four-channel monitor
  • Four-channel monitor that accepts input from proximity and seismic transducers
The Bently Nevada 3500/42M proximity sensor seismic monitor protects machinery by continuously comparing monitored parameters with preset alarm values ​​and transmitting critical machine information to operators and maintenance personnel.

The 3500/42M proximity sensor seismic monitor is a four-channel instrument that receives input signals from both proximity and seismic sensors. It processes these signals, providing vibration and position measurements, and compares the processed signals with user-programmable alarm values.

The 128229-01 Bently Nevada Prox/Seismic I/O Module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
Bently Nevada 128229-01 Prox/Seismic I/O Module Manuals(Datasheets), Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
The processed data is continuously compared to preset alarm and hazard settings; if the measured values ​​exceed these limits, the system will trigger an alarm or take protective measures to prevent equipment damage. Through continuous signal processing and real-time monitoring, this module ensures reliable protection and condition monitoring of critical machinery such as turbines, compressors, and pumps.
1. Machinery Protection:Continuously compares input sensor data with preset alarm settings. If parameters exceed safety limits, protective measures are immediately triggered, such as machine tripping.
 
2. Condition Monitoring:Provides high-resolution data for trend analysis, enabling maintenance teams to identify potential mechanical problems such as wear or misalignment before they lead to unplanned downtime.
 
3. Critical Asset Support:Widely used in industries such as oil and gas, power generation, and petrochemicals to monitor critical rotating equipment, including turbines, compressors, and generators.
 
4. Multi-Function Monitoring:Each channel pair is programmable to perform various specific functions, including:
Radial vibration and thrust position.
Differential expansion and eccentricity.
Acceleration, velocity, and rolling bearing analysis monitoring (REBAM).

Technical notes

The Bentley Nevada 128229-01 is a four-channel proximity/seismic (displacement/seismic vibration) I/O module with built-in terminals, designed for 3500/42M monitoring systems. This module can directly receive 1 to 4 signals from proximity probes, velocity sensors, or accelerometers via its built-in terminals, supporting a wide input voltage range of -10 Vdc to +10 Vdc. It can accurately measure key mechanical parameters such as radial vibration, axial displacement, eccentricity, and differential expansion.
