Description:

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. 

Note: A Keyphasor signal is a once-per-turn or multiple-event-per-turn pulse from a rotating shaft or gear used to 

provide a precise timing measurement. This allows 3500 monitor modules and external diagnostic 

equipment to measure shaft rotative speed and vector parameters such as 1X vibration amplitude and 

phase. 

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 more recent 

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. 

A system with more than four Keyphasor inputs may use a paired configuration 

provided that there are no more than four primary Keyphasor input signals. A 

paired configuration requires two consecutive monitoring positions in either the 

upper/lower or both half-slot positions. Four Keyphasor modules will accept four 

primary and four backup input channels and provide four output channels (one 

per module). A configuration of two paired and one non-paired (three Keyphasor 

modules total) is also possible. In such a configuration, the user may configure 

the one non-paired Keyphasor (order either two 2-channel or one 1-channel and 

one 2-channel option)
