>>>>>型号:IS200VVIBH1CAC 印刷电路板 振动监测板 连接到端子板
【功能描述】
IS200VVIBH1CAC是GE为Mark VI系统制造的印刷电路板。Mark VI是GE以“Speedtronic”名称发布的几种燃气轮机和蒸汽轮机管理系统之一。
该IS200VVIBH1CAC用作振动监测板。该PCB处理来自DVIB或TVIB端子板的振动探头信号。这些探头直接连接到端子板。一块板最多可以连接14个探头。IS200VVIBH1CAC将这些信号数字化，并通过VME总线将其发送到控制器。振动探头用于四种保护功能，包括：
振动。
转子偏心率。
差分扩展。
转子轴向位置
连接到IS200VVIBH1CAC的端子板支持本特利内华达提供的类型的地震探头、近测探头、速度计探头和加速度计探头。在单工或TMR模式下，这些探头的电源均来自IS200VVIBH1CAC板。
IS200VVIBH1CAC包括一个带有三个 LED 指示灯的面板。它们被标记为失败、状态和运行。面板使用三个螺钉连接到PCB表面。该板有两个背板连接器，标记为 P1 和 P2。该板还有四个额外的连接器。该板有几排电感线圈/磁珠，位于 P2 背板的正后方并平行于此，标记为 L1 至 L55。该板还带有各种二极管、电容器和电阻器。组件位于两个电路板表面上。集成电路（超过50个）包括Xilinx Spartan现场可编程门阵列（FPGA）以及多种类型的RAM和SRAM芯片。该组件的技术支持由GE提供。有关更多信息，请参阅MKVI控制系统指南，包括警报、故障代码和可能的原因列表。

【英文介绍】
IS200VVIBH1CAC is a printed circuit board manufactured by GE for the Mark VI system. The Mark VI is one of several gas turbine and steam turbine management systems released by GE under the name Speedtronic.
The IS200VVIBH1CAC is used as a vibration monitoring board. The PCB processes vibration probe signals from DVIB or TVIB terminal boards. These probes are connected directly to the terminal plate. Up to 14 probes can be connected to one board. The IS200VVIBH1CAC digitizes these signals and sends them to the controller via the VME bus. The vibration probe is used for four protection functions, including:
Vibrations.
Rotor eccentricity.
Differential expansion.
Rotor axial position
The terminal board connected to the IS200VVIBH1CAC supports the types of seismic probes, proximity probes, speedometer probes, and accelerometer probes supplied by Bentley Nevada. In simplex or TMR mode, these probes are powered by the IS200VVIBH1CAC board.
The IS200VVIBH1CAC includes a panel with three LED indicators. They are marked as failed, status, and Run. The panel is attached to the PCB surface using three screws. The board has two backplane connectors, labeled P1 and P2. The board also has four additional connectors. The board has several rows of inductors/beads located directly behind and parallel to the P2 backplane, labeled L1 to L55. The board also has a variety of diodes, capacitors and resistors. The components are located on two board surfaces. Integrated circuits (more than 50) include Xilinx Spartan field programmable gate arrays (FPgas) as well as multiple types of RAM and SRAM chips. The technical support for this component is provided by GE. For more information, see the MKVI Control System Guide, including alerts, fault codes, and a list of possible causes.
