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.

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)
