FW352(B)热电偶信号输入卡是一块智能型的、带有模拟量信号调理的八路热电偶信号采集卡。卡件可采集各种型号的热电偶信号及(-20~+20)mV、(-100~+100)mV的电压信号。通道间点点隔离,并可配合端子板完成冷端温度补偿功能,内部冷端补偿范围在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℃。卡件可按1:1冗余配置使用。
℃~+60℃。 The card can be used in 1:1 redundancy configuration.
FW352(B)卡具有热电偶断线检测功能,亦可在测量毫伏信号时禁止断线检测。卡件的前端面板有一组面板指示灯和一个按钮开关。指示灯用于指示卡件的工作状态;按钮开关用于卡件的热插拔,在插拔卡件前,先按住此按钮。卡件后端接有64脚的欧式插针,用于卡件的供电、与数据转发卡的数据交换以及模拟信号的输入等。
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)卡件通过接线端子板采集热电偶信号,并在端子板上进行滤波等前期信号处理,
Fw352 (b) card collects thermocouple signals through the terminal board, and carries out pre signal processing such as filtering on the terminal board,
然后在指定时刻打开该路通道开关,将该路信号进行放大及模/数转换,上送CPU完成信号处理。
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)热电偶信号卡在使用时必须与对应的端子板配合使用,端子板的功用为提供接线通道以及信号前级抗扰动处理。具体情况请参照控制站端子板中对应TB352-U和TB352-RU端子板介绍。
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.
