BENTLYEnhanced Keyphasor Module
Origin: United States
Brand: Bently Nevada
3500/25-01-02-01 Enhanced Keyphasor Module is a half-height, two-channel module that provides Keyphasor signals to 3500 rack monitor modules. When the Keyphasor mark on the shaft aligns with the Keyphasor transducer, the module accepts input signals from proximity probes or magnetic pickups and converts them to digital Keyphasor signals. In a standard setup, the 3500 Machinery Protection System can accept up to four Keyphasor signals, and up to eight Keyphasor signals in a paired arrangement.
Product Introduction
The Enhanced Keyphasor Module is a 3500 system module that has been upgraded. It improves on the previous design's Keyphasor signal processing capabilities while maintaining complete form, fit, and function compatibility with existing Keyphasor modules for usage in older systems.

PWA 125792-01, the Keyphasor module, has been totally replaced by the upgraded 149369-01 module. The 3500 system should use two Keyphasor modules when a system Keyphasor input is required for Triple Modular Redundant (TMR) applications.
The modules work in parallel to deliver both a primary and secondary Keyphasor signal to the other modules in the rack in this setup. A paired arrangement can be used in a system with more than four Keyphasor inputs if there are no more than four major Keyphasor input signals.
Two successive monitoring positions in either the upper/lower or both half-slot positions are required in a paired setup. Four Keyphasor modules will accept four input channels (four primary and four back-ups) and provide four output channels (one per module).
