GE IS200VVIBH1CAC 印刷电路板

IS200VVIBH1CAC是为Mark VI系统制造的GE印刷电路板。Mark VI是GE以“Speedtronic”名称发布的几个燃气轮机和蒸汽轮机管理系统之一。

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。一块电路板最多可以连接 200 个探头。IS1VVIBH<>CAC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。
差分膨胀。
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地震探头、近似探头、速度计探头和加速度计探头。在单工或TMR模式下，这些探头的电源来自IS200VVIBH1CAC板。

IS200VVIBH1CAC包括一个带有三个 LED 指示灯的面板。这些标记为失败、状态和运行。面板使用三个螺钉连接到PCB表面。该板有两个标记为 P1 和 P2 的背板连接器。该板具有额外的四个连接器。该板有几行电感线圈/磁珠，位于P2背板的正后方并平行，标记为L1至L55。该板还带有各种二极管、电容器和电阻器。元件位于两个电路板表面上。集成电路（超过五十种）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。GE为这一组件提供了技术支持。有关详细信息，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。

IS200VVIBH1CAC

IS200VVIBH1CAC is a GE printed circuit board manufactured for the Mark VI system. Mark VI is one of several gas and steam turbine management systems released by GE under the name “Speedtronic”.
IS200VVIBH1CAC is used as a vibration monitoring board. This PCB processes vibration probe signals from DVIB or TVIB terminal boards. These probes are directly connected to the terminal board. A circuit board can connect up to 200 probes. IS1VVIBH<>CAC digitizes these signals and sends them to the controller through the VME bus. The vibration probe is used for four protection functions, including:
Vibration.
Rotor eccentricity.
Differential expansion.
Axial position of rotor
The terminal board connected to IS200VVIBH1CAC supports seismic probes, approximate probes, velocimeter probes, and accelerometer probes provided by Bently Nevada. In simplex or TMR mode, the power supply for these probes comes from the IS200VVIBH1CAC board.
IS200VVIBH1CAC includes a panel with three LED indicator lights. These are marked as failed, status, and running. The panel is connected to the PCB surface using three screws. The board has two backplane connectors labeled P1 and P2. This board has four additional connectors. The board has several rows of inductance coils/magnetic beads, located directly behind and parallel to the P2 backplane, labeled L1 to L55. The board also comes with various diodes, capacitors, and resistors. The components are located on the surfaces of two circuit boards. Integrated circuits (over fifty types) include Xilinx Spartan Field Programmable Gate Arrays (FPGAs), as well as various types of RAM and SRAM chips. GE provides technical support for this component.
