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.

Signal
|
|
Each Keyphasor Module accepts up
|
|
|
|
to two transducer signals from
|
|
|
|
proximity probe transducers or
|
|
|
|
magnetic pickups. The input signal
|
|
|
|
range is +0.8 V to -21.0 V (Non
|
|
|
|
Isolated I/O modules) or +5V to -11V
|
|
|
|
(Isolated I/O modules). Signals
|
|
|
|
exceeding this range are limited
|
|
|
|
internally by the module. Passive
|
|
|
|
magnetic pickups require a shaft
|
|
|
|
rotative speed greater than 200 rpm
|
|
|
|
(3.3 Hz).
