【功能描述】
IS220PVIBH1A的功能是什么？
IS220PVIBH1A是Mark VIe振动监测器I/O包，连接到Mark VIe系统中的端子板。
产品描述
IS220PVIBH1A型号被设计为振动监测器包。PVIB套件的主要功能是在最多两个I/O以太网网络和一个振动端子板之间提供电气接口功能。该套件的主要组件是主处理器板，它与大多数MK VIe分布式I/O包一起使用，以及子板和采集板。
该套件上有13个通道，用于通过以下几种传感器类型收集和读取接近和振动信息：
速度
地震的
邻近器
加速度计
传感器类型用于不同的通道，例如，加速度计仅用于通道1、2和3。请注意，通道9、10、11和12只能用于支持接近器，而第13通道可以输入接近类型或键相信号类型。请注意，IS220PVIBH1A包上的13个差分输入有一个DAC（数字模拟转换器），用于偏置调整，这可能会使信号的直流成分无效，从而更好地使A/D（模数）输入范围居中。
PVIB I/O包具有处理器应用代码，该代码用于可能包含允许该包从单以太网或双以太网输入运行所需的所有逻辑代码。当从两个以太网输入操作时，正确操作IS220PVIBH1A包所需的网络路径始终处于活动状态。如果由于任何原因任一网络发生故障，它不会对I/O包的运行造成任何类型的干扰，但故障将通过运行网络连接指示。

【英文介绍】
The IS220PTURH1B is a component created by GE for its Mark VI system. The Mark VI is one of the final Speedtronic systems released by GE for gas/steam turbine management.
The IS220PTURH1B is a special main trip package for the main turbine. This component provides an electrical interface between the turbine control terminal board and one or two Ethernet networks. The output of this battery pack is performed via a DC-62 pin connector connected to the relevant terminal board.
The IS220PTURH1B comes in a black housing with an air outlet. The front of the housing has multiple LED indicators, as well as an IR (infrared port). This port is not used in this package. Inside this enclosure, there is a processor board, a second board dedicated to turbine control, and an analog acquisition auxiliary board. The battery string is installed on 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 IS220PTURH1B allows automatic reconfiguration and automatic download from the controller to the I/O package. Reconfiguration includes base load, boot load, firmware, and parameters. You must enable automatic reconfiguration to perform this operation. This can be enabled or disabled in the Toolbox ST application through the component editor.
The IS220PTURH1B has an interface with four passive magnetic speed inputs. The circuit sensitivity can detect a rotating gear speed of 2 RPM to determine if the turbine has dropped to zero speed (the turbine has stopped). The median speed signal on the battery pack is used for speed control and primary overspeed trip signals. If you need more information, consult the manufacturer's manual or data sheet.
