              FW352(B)熱電偶信號輸入卡是一塊智能型的、帶有模擬量信號調理的八路熱電偶信號采集卡??刹杉鞣N型號的熱電偶信號及(-20~+20)mV、(-100~+100)mV的電壓信號。通道間點點隔離,并可配合端子板完成冷端溫度補償功能,內部冷端補償范圍在0
              Fw352 (b) thermocouple signal input card is an intelligent eight channel thermocouple signal acquisition card with analog signal conditioning. The card can collect thermocouple signals of various models and voltage signals of (- 20 ~ + 20) MV and (- 100 ~ + 100) MV. The channels are isolated by points, and can cooperate with the terminal board to complete the cold end temperature compensation function. The internal cold end compensation range is 0
              ℃~+60℃??砂?:1冗余配置使用。
              ℃~+60℃。 The card can be used in 1:1 redundancy configuration.
              FW352(B)卡具有熱電偶斷線檢測功能,亦可在測量毫伏信號時禁止斷線檢測??那岸嗣姘逵幸唤M面板指示燈和一個按鈕開關。指示燈用于指示卡件的工作狀態;按鈕開關用于卡件的熱插拔,在插拔卡件前,先按住此按鈕??蠖私佑?4腳的歐式插針,用于卡件的供電、與數據轉發卡的數據交換以及模擬信號的輸入等。
              Fw352 (b) card has thermocouple disconnection detection function, and disconnection detection can also be prohibited when measuring millivolt signal. The front panel of the card has a set of panel indicators and a button switch. The indicator light is used to indicate the working state of the card; The button switch is used for hot plugging of cards. Press and hold this button before plugging cards. The back end of the card is connected with a 64 pin European pin, which is used for power supply of the card, data exchange with data transfer card and analog signal input.

              FW352(B)卡件通過接線端子板采集熱電偶信號,并在端子板上進行濾波等前期信號處理,
              Fw352 (b) card collects thermocouple signals through the terminal board, and carries out pre signal processing such as filtering on the terminal board,
              然后在指定時刻打開該路通道開關,將該路信號進行放大及模/數轉換,上送CPU完成信號處理。
              Then, turn on the channel switch at the specified time, amplify and convert the channel signal, and send it to the CPU to complete signal processing.
              FW352(B)熱電偶信號卡在使用時必須與對應的端子板配合使用,端子板的功用為提供接線通道以及信號前級抗擾動處理。具體情況請參照控制站端子板中對應TB352-U和TB352-RU端子板介紹。
              Fw352 (b) thermocouple signal card must be used together with the corresponding terminal board. The function of the terminal board is to provide wiring channel and signal pre-stage anti-interference processing. For details, please refer to the corresponding tb352-u and tb352-ru terminal boards in the terminal board of the control station.
