Description

The 125800-02 Isolated Keyphasor I/O Module is a half-height, two-channel module for Bently Nevada 3500 racks, designed to provide isolated Keyphasor signals from proximity probes or magnetic pickups to monitor modules. 125800-02 converts input signals (+5 V to -11 V) into digital Keyphasor outputs, with two buffered outputs at the front via coaxial connectors and two at the rear via Euro Style connectors. Transducer power supply is -24 Vdc at 40 mA per channel, and typical power consumption is 3.2 W. Operating temperature ranges from 0°C to +65°C, storage -40°C to +85°C, with 95% non-condensing humidity. Speed/frequency input ranges from 1 to 1,200,000 cpm, output 1–99,999 cpm, and accuracy up to ±1% of cpm at high frequencies. LEDs indicate OK and TX/RX communication with the RIM. 125800-02 supports half-height front slot installation and full-height rear I/O modules, enabling single, paired, or TMR Keyphasor configurations, providing isolated shaft speed and phase signals to multiple automation devices without cross-system interference.

Applications

Provide Isolated Keyphasor Signals to Multiple Modules

125800-02 sends isolated Keyphasor outputs to multiple monitor modules without cross-system interference, supporting automation monitoring of turbines, compressors, and pumps.

Measure Shaft Speed in High-Speed Machinery

Speed/frequency input range up to 1,200,000 cpm allows 125800-02 to track shaft rotation rates in high-speed turbines and generators.

Support TMR and Paired Configurations

In Triple Modular Redundant setups, 125800-02 works with additional modules to provide primary and secondary Keyphasor signals, flagging any channel deviating beyond a configured percentage.

Generate Event Signals for Automation Systems

125800-02 produces once-per-turn event signals from multievent-per-turn inputs, feeding data to process control or predictive maintenance software.
