National Instruments SCXI-1102B 电压输入模块

SCXI-1102B（部件号：776572-02B）具有一个截止频率为200 Hz的三极点低通滤波器、32个差分通道和直流输入耦合。该模块还具有用于温度测量的冷端补偿传感器。该 模 块 的 输入 可 多路 复用 为 一个 输出， 进而 驱动 一个 DAQ 设备 通道。可以使用NI-DAQmx驱动软件和其他应用开发环境（ADE）在设备上开发应用程序，如LabVIEW、LabWindows/CVI或Measurement Studio。

SCXI 1102B的差分输入信号范围为±10 V（增益为100时）或±0.1 V（增益为100时）。差分输入范围是正负通道输入之间可测量的最大电压变化。NI SCXI-1102B 电压 输入 模 块 的 共 模 输入 信号 范围 为 ±10 V。正或负通道输入的共模输入范围是导致精确测量的最大输入电压。 SCXI-1102B模块上的每个通道都带有输入保护电路，可承受无意中施加的电压，峰值为±42 VAC或最大60 VDC。用户应记住，超出差分或共模输入通道范围将导致信号测量不准确。它还可能导致连接的E/M系列DAQ仪器的建立时间增加。

NI SCXI-1102B 电压 输入 模 块 上 的 输入 信号 可以 以 地 为 参考 或 悬 空。在连接热电偶或其他信号之前，用户必须确认它是以地为参考还是浮动。浮动信号必须以地为基准，通过偏置电阻将负通道输入连接到机箱接地。第二种选择是利用某些接线端子（如SCXI-1303）附带的偏置电阻器。NI 设备 配备 了 一个 96 针 公 头 DIN C 前 连接器 和 一个 50 针 公 带 线 后 接头。该设备重 24.6 盎司，尺寸为 1.2 x 6.8 x 8.0 英寸。在物理维度上。

【英文介绍】

National Instruments SCXI-1102B voltage input module

The SCXI-1102B (Part number: 776572-02B) has a three-pole low-pass filter with a cutoff frequency of 200 Hz, 32 differential channels, and DC input coupling. The module also has a cold end compensation sensor for temperature measurement. The input of the module can be multiplexed into an output to drive a DAQ device channel. Applications can be developed on the device using NI-DAQmx driver software and other application development environments (ades), such as LabVIEW, LabWindows/CVI, or Measurement Studio.

The differential input signal range of the SCXI 1102B is ±10 V (for a gain of 100) or ±0.1 V (for a gain of 100). The differential input range is the maximum measurable voltage change between the positive and negative channel inputs. The NI SCXI-1102B voltage input module has a common-mode input signal range of ±10 V. The common-mode input range of the positive or negative channel input is the maximum input voltage that leads to accurate measurement. Each channel on the SCXI-1102B module has an input protection circuit that can withstand unintentionally applied voltage with a peak of ±42 VAC or a maximum of 60 VDC. Users should keep in mind that going outside the differential or common-mode input channel range will result in inaccurate signal measurements. It may also lead to an increase in setup time for connected E/M series DAQ instruments.

The input signal on the NI SCXI-1102B voltage input module can be ground referenced or suspended. Before connecting a thermocouple or other signal, the user must confirm whether it is ground-referenced or floating. The floating signal must be ground based, with a bias resistor connecting the negative channel input to the chassis ground. The second option is to utilize bias resistors that come with certain terminals, such as the SCXI-1303. The NI unit is equipped with a 96-pin male DIN C front connector and a 50-pin male tape line rear connector. The device weighs 24.6 ounces and measures 1.2 x 6.8 x 8.0 inches. In the physical dimension.
