GE/ Bently Nevada 3500/25系列增强型Keyphasor模块是半高双通道模块，用于向3500框架中的监视器模块提供Keyphasor信号。 该模块接收来自接近探头或磁性拾音器的输入信号，并将该信号转换为数字键相器信号，该信号指示轴上的键相器标记何时与键相器传感器重合。3500机械保护系统在正常配置中最多可接受四个Keyphasor信号，在配对配置中最多可接受八个Keyphasor信号。增强型关键相量模块是一个改进的3500系统模块。 它提供了与之前的设计相比，扩展了Keyphasor信号处理能力同时保持完全向下兼容的形式，配合和功能与现有的Keyphasor模块在遗留系统中使用。的Keyphasor模块，PWA 125792-01,完全被最近的149369 – 01年模块。当三模冗余(TMR)需要系统关键相量输入时在应用中, 3500系统应该采用两个Keyphasor模块。

The GE/Bently Nevada 3500/25 Series Enhanced Keyphasor Module is a half height dual channel module used to provide Keyphasor signals to monitor modules in the 3500 rack. This module receives input signals from proximity probes or magnetic pickups and converts them into digital keyphasor signals, which indicate when the keyphasor markings on the shaft coincide with the keyphasor sensor. The 3500 mechanical protection system can accept up to four Keyphasor signals in normal configuration, and up to eight Keyphasor signals in paired configuration. The Enhanced Critical Phasor Module is an improved 3500 system module. It provides an extension of the Keyphasor signal processing capability while maintaining complete downward compatibility compared to previous designs, and is compatible with existing Keyphasor modules for use in legacy systems. The Keyphasor module, PWA 125792-01, was completely replaced by the most recent module of 149369-01. When the third mock examination Redundancy (TMR) requires system critical phasor input, the 3500 system should use two Keyphasor modules in applications.This configuration module works in parallel to provide primary and secondary critical phasor signals to other modules in the rack. Systems with more than four key phasor inputs can use paired configurations, provided that there are no more than four main Keyphasor input signals- A paired configuration requires two consecutive monitoring positions at any upper or lower or two half slot positions. The four key phase modules will accept four main input channels and four backup input channels, and provide four output channels (1 for each module). Two paired and – one non paired configurations (the total number of three key phasor modules) are also possible. In this configuration, users can configure a non paired Keyphasor (order two 2-channel or one 1-channel and one 2-channel option)
