【功能描述】
IS200WNPSH1ABA板是由通用电气制造的印刷电路板，用于Mark VI涡轮机控制系统。该模型可以被视为子板，并且可以与该系统中的其他板连接。该板没有像Mark VI系列中的许多其他板那样具有任何类型的LED标识符。WDII板上有16个保险丝，分为两排，每排8个。它们位于电路板顶部的两个母插头连接器旁边。
当IS200WNPSH1ABA板用于Mark VI系统时，它可以与多个潜在的通用或特定应用I/O一起使用。WDII板可用于单工、双工或三工模块化冗余应用，通常Mark VI系列型号的应用类型为三模冗余。三重模块化冗余架构将有三个独立的模块，即控制模块、备份保护模块和IONet。

【英文介绍】
The IS200VTURH1BAA board is part of the GE Mark VI Speedtronic system. This control system is used for the control and maintenance of steam or gas industrial turbines.
IS200VTURH1BAA is a main turbine protection card. It has a variety of features, including:
Controls (3) overspeed trip relays located on the TRPx terminal board. The board has nine magnetic relays interconnected with three trip solenids. In a TMR system, all nine relays are used. In a simplex system, only three relays are used.
Monitor (8) Geiger-Mueller flame detector. These are for gas turbine applications only.
Monitor induction shaft current and voltage
Turn off the main circuit breaker/provide automatic generator synchronization.
The turbine speed is measured using (4) passive pulse rate devices.
The IS200VTURH1BAA can be installed in the VME processor rack only when the power is off. The board should be pushed in using top and bottom pull rods to secure the edge connectors. The board is then secured to its position in the rack system using external screws (top and bottom). The narrow front panel contains only these additional screws, a D-housing connector, and three LED indicators. These indicators are labeled Status, Fail, and Run.
The board is designed to measure turbine speed with up to four pulse rate signals. This is in simplex applications. The board can also be used for TMR applications, but the way the signal is picked up is different.
