Bentley Nevada 125800-01 Keyphasor I/O Module
1. Product Description
The Bentley Nevada 125800-01 is a high-performance Keyphasor I/O module designed for the 3500 Series machinery protection system. This half-height, two-channel module receives and processes keyphasor signals from rotating machinery, such as turbines and compressors, enabling precise speed measurement, vibration analysis, and phase synchronization. By converting analog keyphasor inputs into digital signals, the 125800-01 ensures real-time monitoring and early fault detection, enhancing operational reliability in critical industrial environments.

4. Application Areas and Case Studies
Industries:
- Power generation (gas/steam turbines)
- Oil and gas (pumps, compressors)
- Manufacturing (rotating machinery)
Case Study:
A U.S. petrochemical plant integrated the 125800-01 to monitor compressor keyphasor signals. By detecting misalignment in real time, the module prevented a potential $300,000 breakdown and reduced maintenance costs by 20%.
