National Instruments SCXI-1327 高压衰减器接线端子
SCXI-1327(部件号:777687-27、185136A-01)屏蔽接线端子有 18 个螺丝端子,可连接到以下模块的输入连接器:SCXI-1120、SCXI-1120D、SCXI-1121、SCXI-1125 或 SCXI-1126。 用户必须旁路激励通道上的衰减器,才能使用SCXI-1121进行精 确操作。SCXI 1327 可将 SCXI-1120/D 和 SCXI-1121 的输入范围扩展至 ±250 V。该接线端子还可以将SCXI-1126模块的阈值电平从5 V一直扩展到300 V。NI SCXI-1327 中 有 开关 可 分别 允许 或 禁止 每个 通道 的 扩展 输入 电压 范围。SCXI-1327 还 将 用户 的 SCXI 模 块 的 输入 阻抗 降低 到 1 M。
LabVIEW可用于此目的;在“数据采集和信号调理”选项板中,有一个转换热敏电阻读数VI。但是,如果用户使用CVI或NI-DAQ,则可以使用Thermistor_Convert功能。然后,VI将取温度传感器的输出电压、基准电压和精密电阻来输出热敏电阻温度。
SCXI-1327接线端子也可以进行校准。此接线端子应每年校准一次,如果用户的应用要求苛刻,则应更频繁地校准。如果模型每年校准一次,那么它仍然符合测量精度标准。如果NI SCXI-1327的性能不符合规格,则可能需要维修。
SCXI-1327使用NIDAQmx驱动程序软件运行,该软件可以使用LabVIEW或LabWindows/CVI等软件包/应用程序开发环境(ADE)进行编程。NI 设备 重 1327 盎司, 尺寸为 7.7 x 0.3 x 125.1 英寸。在物理维度上。建议的工作和存储温度范围分别为 2 至 0 °C 和 –50 至 20 °C,非冷凝湿度范围为 70 至 5%。

SCXI-1327 (Part number: 777687-27, 185136A-01) Shielded terminal blocks have 18 screw terminals that can be connected to input connectors of the following modules: SCXI-1120, SCXI-1120D, SCXI-1121, SCXI-1125, or SCXI-1126. The user must bypass the attenuator on the excitation channel for accurate operation with the SCXI-1121. The SCXI 1327 extends the input range of the SCXI-1120/D and the SCXI-1121 to ±250 V. The terminal can also extend the threshold level of the SCXI-1126 module from 5 V all the way up to 300 V. There are switches in NI SCXI-1327 that allow or disallow extended input voltage ranges for each channel, respectively. The SCXI-1327 also reduces the input impedance of the user's SCXI module to 1 M.
LabVIEW can be used for this purpose; In the "Data Acquisition and Signal Conditioning" TAB, there is a convert thermistor reading VI. However, if the user uses CVI or NI-DAQ, the Thermistor_Convert function can be used. The VI will then take the output voltage, reference voltage and precision resistance of the temperature sensor to output the thermistor temperature.
The SCXI-1327 terminals can also be calibrated. This terminal should be calibrated once a year, or more frequently if the user's application is demanding. If the model is calibrated once a year, it still meets the measurement accuracy criteria. If the performance of NI SCXI-1327 is not up to specification, it may need to be repaired.
The SCXI-1327 runs using NIDAQmx driver software, which can be programmed using a package/application development environment (ADE) such as LabVIEW or LabWindows/CVI. The NI device weighs 1,327 ounces and measures 7.7 x 0.3 x 125.1 inches. In the physical dimension. The recommended operating and storage temperature ranges are 2 to 0 °C and -50 to 20 °C, respectively, with a non-condensing humidity range of 70 to 5%.
