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.
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 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 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)
The Isolated Keyphasor I/O module is designed for applications where the Keyphasor signals are tied in parallel to multiple devices and require isolation from other systems, such as a control system. The Isolated I/O module was created specifically for Magnetic Pickup applications but is compatible with and will provide isolation for Proximitor* applications as long as an external power supply is provided.
The intent of this I/O module was primarily to measure shaft speed and not phase. The module can provide phase measurements, but this I/O introduces a slightly higher phase shift than the Non-Isolated I/O version. Figure 1 shows the amount of phase shift that the Isolated I/O modules will add at different machine speeds.
Enhanced product features include generation of once-per-turn event signals from multi-event-per-turn inputs, field-upgradeable firmware, and asset management data reporting.
