Bently Nevada 3500/25 Enhanced Keyphaser Module

The Bently Nevada Enhanced Keyphasor Module is a half-height, two-channel module that provides Keyphasor signals to monitor modules in a 3500 rack. It receives inputs from proximity probes or magnetic pickups and converts them into digital Keyphasor signals, indicating when the Keyphasor mark on the shaft aligns with the transducer. The 3500 Machinery Protection System can accept up to four Keyphasor signals in a standard configuration and up to eight in a paired configuration.

This Enhanced Keyphasor Module improves on the previous design by offering expanded signal processing capabilities while remaining fully compatible in form, fit, and function with existing Keyphasor modules. It replaces the older PWA 125792-01 module with the updated 149369-01 module, ensuring seamless integration into legacy systems.
