3500/25 Enhanced Keyphasor Module 3500/25-01-01-00 149369-01
125800-01Description 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.
