SCXI-1104/C/D模块是NI仪器仪表信号调理扩展（SCXI）系列的成员，设计用于NI数据采集（DAQ）设备。这些模块设计用于中压信号的信号调理 - 30VAC、±42VAC、±60VDC。SCXI-1104/C/D模块均方根峰值有32个差分模拟输入通道。每个通道在放大器之前还有一个 10 分频衰减器级。用户 可 将 SCXI-1104/ C 输入 多路 复用 到 驱动 DAQ 设备 输入 通道 的 单个 模 块 输出。

National Instruments SCXI-1104D是一款电压输入模块，设计用于对更高电压信号进行信号调理。SCXI-1104D配备32个差分通道，允许在所有输入通道上传输完整信号。如果您 打算 在 带状 电缆 多 机 箱 SCXI 系统 中使用 NI SCXI-1104D， 则需要 将 SCXI-1346 多 机箱 适配器 与 它 一起使用。但是，如果您不想自动检测 SCXI 模块，则可以单独添加模块。

该器件最显着的特性之一是能够将引脚 1、2、4 或 19 排列到电压输入模块的模拟接地，同时使用软件。这为用户提供了将连接到模拟接地的引脚用作SCXI-1104D的模拟电源接地连接点的选项。必须记住，NI SCXI-1104D模拟输出没有过电压保护，因此连接到此输出的任何外部电压都可能造成损坏。

建议在操作设备前预热 20 分钟，该设备的工作温度范围为 0 至 50 °C。 建议每年至少重新校准一次设备，或者在指定温度范围之外的任何时候重新校准设备。该器件具有一个 50 针带状电缆背面连接器和一个 96 针 DIN C 正面公头连接器。

±42 VAC/±60 VDC voltage range

SCXI-1104:2 Hz Bandwidth

SCXI-1104C: 10 kHz bandwidth

The SCXI-1104/C/D module is a member of the NI Instrumentation Signal Conditioning Extension (SCXI) family and is designed for use in NI Data acquisition (DAQ) equipment. These modules are designed for signal conditioning of medium voltage signals - 30VAC, ±42VAC, ±60VDC. The SCXI-1104/C/D module has 32 differential analog input channels for RMS peak. Each channel also has a 10 division attenuator stage before the amplifier. Users can multiplex the SCXI-1104/ C input to a single module output that drives the input channel of the DAQ device.

The National Instruments SCXI-1104D is a voltage input module designed for signal conditioning of higher voltage signals. The SCXI-1104D is equipped with 32 differential channels, allowing full signal transmission across all input channels. If you plan to use the NI SCXI-1104D in a strip-cable multi-box SCXI system, you will need to use the SCXI-1346 multi-box adapter with it. However, if you do not want to automatically detect SCXI modules, you can add modules separately.

One of the most remarkable features of the device is the ability to line up pins 1, 2, 4 or 19 to the analog ground of the voltage input module while using software. This gives the user the option to use the pins connected to the analog ground as the analog power ground connection point for the SCXI-1104D. It is important to remember that the NI SCXI-1104D analog output is not protected by overvoltage, so any external voltage connected to this output can cause damage.

It is recommended to preheat the device for 20 minutes before operating the device. The operating temperature of the device ranges from 0 to 50 °C. It is recommended to recalibrate the device at least once a year, or at any time outside the specified temperature range. The device has a 50-pin ribbon cable back connector and a 96-pin DIN C front male connector.
