140471-01 本特利位移监测模块

3500系统能提供连续、在线监测功能，适用于机械保护应用，并为早期识别机械故障提供重要的信息。

系统的工作流程是：从现场取得的传感器输入信号提供给3500监测器框架内的监测器和键相位通道，数据被采集后，与报警点比较并从监测器框架送到一个地方或多个地方处理。 

3500框架中模件的共同特征是带电插拔和内部、外部接线端子。任何主模件（安装在3500框架前端）能够在系统供电状态中拆除和更换而不影响不相关模块的工作，如果框架有两个电源，插拔其中一块电源不会影响3500框架的工作。

外部端子使用多芯电缆（每个模块一根线）把输入\输出模块与终端连接起来，这些终端设备使得在紧密空间内把多条线与框架连接起来变的非常容易，内部端子则用于把传感器与输入\输出模块直接连接起来。外部端子块一般不能与内部端子输入/输出模块一起使用。

The 3500 system provides continuous, on-line monitoring for mechanical protection applications and provides important information for early identification of mechanical failures.

The work flow of the system is: the sensor input signal obtained from the field is provided to the monitor and key phase channel in the 3500 monitor frame, and the data is collected, compared with the alarm point and sent from the monitor frame to one or more places for processing. 

The common features of the modules in the 3500 frame are live plug and plug and internal and external terminals. Any main module (mounted on the front end of the 3500 frame) can be removed and replaced in the system power supply state without affecting the operation of unrelated modules, and if the frame has two power supplies, plugging and unplugging one of them will not affect the operation of the 3500 frame.

The external terminals use multi-core cables (one wire per module) to connect the input/output module to the terminal, which makes it very easy to connect multiple lines to the frame in a tight space, and the internal terminals are used to connect the sensor directly to the input/output module. The external terminal block generally cannot be used with the internal terminal input/output module.
