3500/25增強型Keyphasor模塊是一個半高雙通道模塊用于向中的監(jiān)視器模塊提供鍵相器信號的模塊3500架。該模塊接收來自近程探頭的輸入信號磁性拾取并將信號轉換成數(shù)字鍵控信號，該信號指示軸上的鍵相標記何時與鍵相傳感器。3500機械保護系統(tǒng)可以接受正常配置最多四個鍵相器信號，最多八個成對配置的鍵相器信號。

增強型關鍵相量模塊是一個改進的3500系統(tǒng)模塊。它提供了與之前的設計相比，擴展了Keyphasor信號處理能力同時保持完全向下兼容的形式，配合和功能與現(xiàn)有的Keyphasor模塊在遺留系統(tǒng)中使用。的Keyphasor模塊，PWA 125792-01，完全被最近的149369 – 01年模塊。
當三模冗余(TMR)需要系統(tǒng)關鍵相量輸入時在應用中，3500系統(tǒng)應該采用兩個Keyphasor模塊。在這個配置模塊并行工作，以提供主和次要的關鍵相量信號到機架中的其他模塊。有四個以上關鍵相量輸入的系統(tǒng)可以使用配對配置前提是不超過四個主要的Keyphasor輸入信號。一個配對配置需要兩個連續(xù)的監(jiān)測位置在任何上/下或兩個半槽位置。四個關鍵相位模塊將接受四個主輸入通道和4個備份輸入通道，并提供4個輸出通道(1每個模塊)。兩個成對和一個非成對的構型(三個關鍵相量模塊總數(shù))也是可能的。在這樣的配置中，用戶可以進行配置一個非配對的Keyphasor(訂購兩個2通道或一個1通道和一個2通道選項)
隔離鍵相器I/O模塊是為應用程序設計的關鍵相量信號與多個設備并行連接，需要隔離來自其他系統(tǒng)，如控制系統(tǒng)。隔離I/O模塊為專為磁性拾取應用而創(chuàng)建，但與和兼容只要有外部電源，將為Proximitor*應用程序提供隔離供應是提供的。注意，這個I/O模塊的主要目的是測量軸轉速，而不是相位。該模塊可以提供相位
但是這種I/O引入的相移比非隔離I/O版本略高。圖1顯示了隔離的相移量I/O模塊將以不同的機器速度添加。增強的產(chǎn)品功能包括生成每回合一次的事件信號從多事件每回合輸入，現(xiàn)場升級固件，和資產(chǎn)管理數(shù)據(jù)報表。

The 3500/25 Enhanced Keyphasor module is a semi-high dual channel module used to provide the key phaser signal to the monitor module 3500. The module receives the input signal from the short-range probe magnetic pick up and converts the signal into a digital keying signal that indicates when the key phase marker on the axis is with the key phase sensor. The 3500 mechanical protection system can accept up to four key-phase signals in normal configurations and up to eight key-phase signals in paired configurations.

The Enhanced Critical phasor module is an improved 3500 system module. It offers extended Keyphasor signal processing capabilities compared to previous designs while maintaining a fully backward compatible form that fits and functions with existing Keyphasor modules for use in legacy systems. The Keyphasor module, PWA 125792-01, was completely replaced by the most recent 149369-01 module.
When three-mode redundancy (TMR) requires system critical phasor inputs in an application, the 3500 system should adopt two Keyphasor modules. 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 a paired configuration provided that there are no more than four major Keyphasor input signals. A paired configuration requires two consecutive monitoring positions at any up/down or two half-slot positions. The four critical phase modules will accept four primary input channels and four backup input channels, and provide four output channels (1 per module). Two paired and one unpaired configurations (the total number of three key phasor modules) are also possible. In such a configuration, the user can configure a non-paired Keyphasor(order two 2-channel or one 1-channel and one 2-channel option).
Isolated key phase I/O modules are designed for applications where critical phasor signals are connected in parallel with multiple devices and need to be isolated from other systems, such as control systems. Isolated I/O modules have been created specifically for magnetic pickup applications, but are compatible with and will provide isolated supplies for Proximitor* applications as long as an external power supply is available. Note that the primary purpose of this I/O module is to measure shaft speed, not phase. This module can provide phase
However, this I/O introduces a slightly higher phase shift than the non-isolated I/O version. Figure 1 shows the isolated phase-shift amount of I/O modules that will be added at different machine speeds. Enhanced product features include generating once-per-turn event signals from multi-event per-turn inputs, on-site firmware upgrades, and asset management data reports.
