Product 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.
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.
