IS220PTURH1A GE 蒸汽轮机模块

产品说明

IS220PRTDH1A是GE为其Mark VI系统开发的组件。Mark VI是GE发布的用于燃气/蒸汽轮机管理的Speedtronic系统之一。

IS220PRTDH1A是一次汽轮机专用一次跳闸组件。该组件在汽轮机控制端子板和一个或两个以太网之间提供电气接口。该组件的输出通过连接到相关端子板的DC 62针连接器实现。

IS220PRTDH1A采用黑色外壳，带有空气流通开口。这种情况下的前面有多个LED指示灯，以及一个IR(红外端口。)这个端口没有在这个包中使用。在这个外壳内，有一个处理器板、一个专用于涡轮机控制的第二块板和一个模拟采集辅助板。电池组安装在TTURH1C端子板上。处理器板有两个10/100以太网端口、闪存和RAM、一个用于识别的只读芯片、一个内部温度传感器和一个复位电路。

IS220PRTDH1A允许自动重新配置，自动从控制器下载到I/O包。重新配置包括基本加载、引导加载、固件和参数。要实现这一点，必须启用自动重新配置。这可以通过组件编辑器在工具箱ST应用程序中启用或禁用。

IS220PRTDH1A具有一个带有四个无源磁速度输入的接口。电路灵敏度可允许检测2 RPM盘车装置速度，以确定涡轮机是否已降至零速度(涡轮机已停止)。)机组上的中间速度信号用于速度控制和主要超速跳闸信号。如果需要更多信息，请查阅制造商的手册或数据表。

Product Description

The IS220PRTDH1A is a component created by GE for their Mark VI system.  The Mark VI is one of the final Speedtronic systems for gas/steam turbine management that was released by GE.

The IS220PRTDH1A is a Primary Turbine Specific Primary Trip pack.  This component provides an electrical interface between a turbine control terminal board and either one or two Ethernet networks.  Outputs from this pack occur through a DC-62 pin connector that connects to an associated terminal board.

The IS220PRTDH1A is built with a black outside casing with openings for air circulation.  The front of this case has multiple LED indicators, as well as an IR (infrared port.) This port is not used in this pack.  Inside this casing, there is a processor board, a second board specific to turbine control, and an analog acquisition auxiliary board.   The pack mounts to the TTURH1C terminal board. The processor board has two 10/100 Ethernet ports, flash memory, and RAM, a read-only chip for identification, an internal temperature sensor, and a reset circuit.

The IS220PRTDH1A allows for Auto-reconfiguration, which will automatically download from the controller to the I/O pack.  The reconfiguration includes baseload, bootload, firmware, and parameters. Auto-reconfiguration must be enabled for this to occur.  This is enabled or disabled in the Toolbox ST application through the Component Editor.

The IS220PRTDH1A has an interface with four passive, magnetic speed inputs.  Circuit sensitivity can allow detection of 2-RPM turning gear speed to determine if the turbine has dropped to zero speed (turbine has stopped.)  The median speed signal on the pack is used for speed control and for primary overspeed trip signal. Consult manuals or datasheets from the manufacturer if you need more information.
IS220PAICH1A是一款在GE Mark VI系列下开发的模拟I/O Pack。单工和三重模块冗余 (TMR) Mark VI 控制系统可用于小型应用和大型集成系统，控制范围从单个模块到多个分布式模块。该系统的吞吐量允许在 40 毫秒内操作多达 9 个 21 插槽 VME 机架的 I/O 板，包括数据投票。在一种称为软件实现容错的方法中，输入在软件中进行投票 (SIFT)。每个控制模块的 VCMI 板通过其自己的 IONet 从控制模块背板和其他模块获取输入。

除了通用 I/O 之外，Mark VI 还拥有许多专为与特定传感器和执行器直接通信而设计的板。在许多情况下，这可以大限度地减少或消除大量的插入仪器。因此，消除了关键区域中许多可能的单点故障，从而提高了运行可靠性并降低了长期维护成本。由于与传感器和执行器的直接连接，诊断还可以直接询问设备上的装置，以获得效果。此信息用于评估设备和系统的性能。外围仪表的消除减少了备件库存，这是这种设计的一个微妙的好处。
