3500/25-01-01-00不超过四个主要键相器输入 信号
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 nonpaired (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)
The Isolated Keyphasor I/O module is designed
for applications where the Keyphasor signals
are tied in parallel to multiple devices and
require isolation from other systems, such as
a
control system. The Isolated I/O module was
created specifically for Magnetic Pickup
applications but is compatible with and will
provide isolation for Proximitor* applications as
long as an external power supply is provided.
The intent of this I/O module was primarily to
measure shaft speed and not phase. The
module can provide phase measurements, but
this I/O introduces
a slightly higher phase shift
than the Non-Isolated I/O version. Figure
1
shows the amount of phase shift that the
Isolated I/O modules will add at different
machine speeds.
具有四个以上键相器输入的系统
可以使用
那里提供了配对配置
不超过四个主要键相器输入
信号。
成对配置需要两个
在任一
上/下或两个半槽位置。四
键相器模块将接受四个主要模块
和四个备用输入通道，并提供
四个输出通道（每个模块一个）。
A.
两个成对和一个非成对（总共三个键相模块）的配置也是
可能的在这种情况下
配置，用户可以
配置一个非配对键相器
（订购两个2通道或一个1通道
和一个2通道选项）
设计了隔离键相器输入/输出模块
用于键相器信号
并行连接到多个设备，并且
控制系统。隔离I/O模块
专为磁性拾取器设计
应用程序，但与兼容
为Proximitor*应用程序提供隔离
只要提供外部电源即可。
此I/O模块的目的主要是
测量轴速度，而不是相位。这个
模块可以提供相位测量，但是
该I/O引入
稍高的相移
而非隔离I/O版本。
