Description
Bentley Nevada 125680-01 Proximitor I/O Module
The
Bentley Nevada 125680-01 is a compact, half-height Proximitor I/O module designed for the 3500 Series machinery protection system. It interfaces with proximity probes and magnetic pickups to monitor critical parameters such as vibration, displacement, and shaft speed in rotating equipment like turbines, compressors, and pumps. With dual-channel capabilities and advanced signal conditioning, the
125680-01 converts raw sensor data into actionable insights, enabling predictive maintenance and minimizing downtime.

- Multi-Function Monitoring: Supports radial vibration, thrust position, and eccentricity measurements in a single module.
- Redundancy Support: Dual-channel design allows parallel operation for critical systems requiring 100% uptime.
- Precision Signal Conditioning: Reduces noise and ensures ±0.1% accuracy for reliable machinery health assessment.
- Hot-Swap Capability: Modules can be replaced without powering down the system, enhancing operational flexibility.
Industries:
- Power generation (gas/steam turbines)
- Oil and gas (pumps, compressors)
- Manufacturing (rotating machinery)
Case Study:
A U.S. petrochemical plant deployed the 125680-01 to monitor compressor vibrations. By detecting a developing bearing fault through real-time displacement analysis, the plant avoided a $200,000 emergency repair and extended equipment lifespan by 24 months.
The 125680-01 outperforms standard I/O modules with:
- Integrated Communication: Built-in RS485 support eliminates external converters.
- Enhanced Diagnostic Tools: Advanced self-testing and sensor failure detection reduce false alarms.
- Space Efficiency: Half-height form factor occupies 30% less rack space than comparable dual-channel solutions.
- System Requirements: Verify compatibility with 3500/40M racks and sensor types (eddy current/magnetic).
- Environmental Needs: Opt for IP66-rated enclosures for outdoor or corrosive environments.
- Redundancy Strategy: Pair with additional modules for triple modular redundant (TMR) configurations.
- Installation: Follow ESD protocols and secure wiring to prevent signal interference.
- Calibration: Perform sensor calibration every 6 months using Bentley Nevada-approved tools.
- Software Updates: Regularly update firmware to access new diagnostic features and security patches.
