3500/25 Enhanced Keyphasor module

The 3500/25 Enhanced Keyphasor module is a half-height, dual-channel module designed to provide Keyphasor signals to monitoring modules in the 3500 rack. The module is capable of receiving input signals from proximity probes or magnetic pickups and converting them into digital Keyphasor signals. These signals are used to indicate when the Keyphasor mark on the axis overlaps with the Keyphasor sensor.

The 3500 machine protection system can accept up to four Keyphasor signals in a daily configuration and up to eight in a paired configuration. A Keyphasor signal is a pulse signal generated by a rotating shaft or gear once per revolution or once for multiple events to provide accurate timing measurements. This enables the 3500 monitoring module and external diagnostic equipment to measure the rotation speed of the shaft and vector parameters such as 1X vibration amplitude and phase.

This enhanced Keyphasor module is an improved version of the 3500 system module that provides more powerful Keyphasor signal processing capabilities than previous designs, while maintaining full backward compatibility with existing Keyphasor modules in form, fit, and function for use in older systems. The original Keyphasor module PWA 125792-01 has been completely replaced by the updated module 149369-01.

In triple modular redundancy (TMR) applications that require system Keyphasor inputs, the 3500 system should use two Keyphasor modules. In this configuration, the modules work in parallel, providing primary and secondary Keyphasor signals to other modules in the rack. If the system requires more than four Keyphasor inputs, it can be configured in pairs with no more than four major Keyphasor input signals. A paired configuration requires two consecutive monitoring positions in either the upper/lower or two half-slot positions.

Overall, the 3500/25 enhanced Keyphasor module provides important support for condition monitoring and protection of mechanical equipment with its efficient and reliable performance. Whether in daily or paired configurations, it accurately delivers Keyphasor signals, ensuring stable operation and accurate measurement of the system.
