Product Dimensions：

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.

Keyphasor signal is a once-per-turn or multipleevent-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 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.

A system with more than four Keyphasor inputs may use a

paired configuration provided there are no more than four
