3500-25-149369-01 用于向3500机架中的监视器模块提供Keyphasor信号

3500-25-149369-01是一种半高、双通道模块，用于向3500机架中的监视器模块提供Keyphasor信号。该模块接收来自近接探头或磁性拾音器的输入信号，并将这些信号转换为数字Keyphasor信号，以指示轴上的Keyphasor标记何时与Keyphasor传感器相一致。这种模块的设计使得它能在扩展的键相信号处理能力方面超越以前的设计，同时保持与现有Keyphasor模块的完全向下兼容性。

在3500机械保护系统中，最多可接受四个Keyphasor信号以实现正常配置，而在配对配置下最多可接受八个Keyphasor信号。键相位信号是来自旋转轴或齿轮的每转一次或每转多次的脉冲信号，它提供精确的时间测量，并允许3500监测器模块和外部故障诊断设备测量诸如1X幅值和相位等向量参数。

3500-25-149369-01还具有缓冲的传感器输出功能，可以通过同轴接头或欧式接头获得。此外，模块内还有发光二极管（OK指示灯）可以指示在键相器模块内检测到一个故障，以及一个通信指示灯，当键相器模块与框架接口模块（RIM）进行通讯时会发出指示。

The 3500-25-149369-01 is a half-height, dual-channel module that provides Keyphasor signals to monitor modules in the 3500 rack. The module receives input signals from proximity probes or magnetic pickups and converts these signals into digital Keyphasor signals to indicate when the Keyphasor mark on the shaft is aligned with the Keyphasor sensor. The design of this module enables it to surpass previous designs in terms of extended key signal processing power while maintaining full backward compatibility with existing Keyphasor modules.

In the 3500 mechanical protection system, up to four Keyphasor signals can be accepted for normal configuration, and up to eight Keyphasor signals can be accepted in the paired configuration. The key phase signal is a pulse signal from the rotating shaft or gear once or many times per revolution, which provides accurate time measurement and allows 3500 monitor modules and external fault diagnosis equipment to measure vector parameters such as 1X amplitude and phase.

The 3500-25-149369-01 also features a buffered sensor output, which can be obtained via a coaxial or European connector. In addition, there is a light-emitting diode (OK indicator) within the module to indicate that a fault has been detected within the key phaser module and a communication indicator to indicate when the key phaser module is communicating with the Frame Interface module (RIM).
