【功能描述】
IS220PVIBH1A的功能是什么？
IS220PVIBH1A是Mark VIe振動監(jiān)測器I/O包，連接到Mark VIe系統(tǒng)中的端子板。
產品描述
IS220PVIBH1A型號被設計為振動監(jiān)測器包。PVIB套件的主要功能是在最多兩個I/O以太網網絡和一個振動端子板之間提供電氣接口功能。該套件的主要組件是主處理器板，它與大多數MK VIe分布式I/O包一起使用，以及子板和采集板。
該套件上有13個通道，用于通過以下幾種傳感器類型收集和讀取接近和振動信息：
速度
地震的
鄰近器
加速度計
傳感器類型用于不同的通道，例如，加速度計僅用于通道1、2和3。請注意，通道9、10、11和12只能用于支持接近器，而第13通道可以輸入接近類型或鍵相信號類型。請注意，IS220PVIBH1A包上的13個差分輸入有一個DAC（數字模擬轉換器），用于偏置調整，這可能會使信號的直流成分無效，從而更好地使A/D（模數）輸入范圍居中。
PVIB I/O包具有處理器應用代碼，該代碼用于可能包含允許該包從單以太網或雙以太網輸入運行所需的所有邏輯代碼。當從兩個以太網輸入操作時，正確操作IS220PVIBH1A包所需的網絡路徑始終處于活動狀態(tài)。如果由于任何原因任一網絡發(fā)生故障，它不會對I/O包的運行造成任何類型的干擾，但故障將通過運行網絡連接指示。

【英文介紹】
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.
