3500/25-02-01-00 Bently Nevada Enhanced Keyphasor Module 

The 3500/25 Enhanced Keyphasor Module is a half-height, two-channel module used to provide Keyphasor signals to the monitor modules in a 3500 rack. The module receives
input signals from proximity probes or magnetic pickups and converts the signals to digital Keyphasor signals that indicate when the Keyphasor mark on the shaft coincides with the
Keyphasor transducer. The 3500 Machinery Protection System can accept up to four Keyphasor signals for normal configuration and up to eight Keyphasor signals in a paired
configuration.

The Enhanced Keyphasor Module is an improved 3500 system module. It offers expanded Keyphasor signal processing capabilities over the previous design while maintaining complete downward-compatibility in terms of form, fit and function with existing Keyphasor modules for use in legacy systems. The Keyphasor module, PWA 125792-01, is completely replaced by the updated 149369-01 module.

When a system Keyphasor input is required for Triple Modular Redundant (TMR) applications, the 3500 system should employ two Keyphasor modules. In this configuration, the modules work in parallel to provide both a primary and secondary Keyphasor signal to the other modules in the rack.

3500/25 Functional Description：
-For regular setup, the 3500 Machinery Protection System can accept up to four Keyphasor signals, and for paired configuration, it can accept up to eight.
-A spinning shaft or gear's once-per-turn or multiple-event-per-turn pulse known as a keyphasor signal can be used to detect timing precisely.
-As a result, shaft rotative speed and vector characteristics like 1X vibration amplitude and Phase can be measured by 3500 monitor modules and external diagnostic tools.

Enhanced Keyphasor Module：
-An enhanced 3500 system module is called the Enhanced Keyphasor Module. While maintaining full downward compatibility in terms of shape, fit, and function with existing Keyphasor modules for usage in legacy systems, it offers increased Keyphasor signal processing capabilities over the prior design. The revised 149369-01 module totally replaces the Keyphasor module, PWA 125792-01.
-The 3500 system should use two Keyphasor modules whenever a system Keyphasor input is required for Triple Modular Redundant (TMR) applications. In this setup, the modules operate in parallel to give the other modules in the rack a primary and secondary Keyphasor signal.
-If there are no more than four primary Keyphasor input signals, a system with more than four Keyphasor inputs may use a paired arrangement.
