National Instruments SCXI-1124 模拟量输出模块

SCXI-1124（部件号：776572-24）是一款6通道隔离模拟输出模块，用于静态DC（低带宽）电压或电流信号。一个通道的最大更新速率为 555 S/s，所有六个通道的最大更新速率为每通道 125 S/s。NI SCXI-1124 集成 了 6 个 自主 隔离 的 12 位数模 转换器 （DAC） 通道。用户可以安排每个通道进行电压或电流输出。对于电压，用户可以选择三个单极性或三个双极性范围中的任何一个。对于电流，每个通道输出 0 至 20 mA。

该模拟输出模块可通过软件进行配置，并集成本地可用的 EEPROM，用于保存校准常数。该模块非常适合需要受限电压或电流输出来控制程序的应用。对于更多通道，用户可以在SCXI框架中使用一些NI SCXI 1124模块，以及其他信号调理I/O模块。

使用此模块，用户可以针对以下电压输出范围对每个通道进行软件编程：0 至 1、0 至 5、0 至 10、±1、±5 或 ±10 V。在单个模块中，用户可以逐步关联通道，使每个模块的输出信号高达 60 VDC。每个电压通道都集成了一个低阻抗输出缓冲器，可驱动高达5 mA的电流。

SCXI-1124使用NI-DAQmx驱动软件运行，该软件与LabVIEW、LabWindows/CVI或Measurement Studio等软件包/应用开发环境（ADE）兼容。

32 channel, ±60 VDC, 10 kHz filter, voltage input module for SCXI - SCXI 1104C is designed for signal conditioning of high voltage signals. It has a 10 kHz cut-off frequency filter. All channels Multiplexes a single channel that controls a DAQ device, thereby increasing the number of channels in a DAQ system.

National Instruments SCXI-1124 analog output module

The SCXI-1124 (Part number: 776572-24) is a 6-channel isolated analog output module for static DC (low bandwidth) voltage or current signals. The maximum update rate for one channel is 555 S/s and the maximum update rate for all six channels is 125 S/s per channel. The NI SCXI-1124 integrates six autonomously isolated 12-bit digital-to-analog converter (DAC) channels. The user can arrange each channel for voltage or current output. For voltage, the user can choose any of three unipolar or three bipolar ranges. For current, each channel outputs 0 to 20 mA.

The analog output module can be configured via software and integrates a locally available EEPROM for storing calibration constants. The module is ideal for applications that require a limited voltage or current output to control a program. For more channels, users can use some NI SCXI 1124 modules in the SCXI framework, as well as other signal conditioning I/O modules.

With this module, users can software program each channel for the following voltage output ranges: 0 to 1, 0 to 5, 0 to 10, ±1, ±5, or ±10 V. In a single module, users can gradually associate channels so that the output signal of each module is up to 60 VDC. Each voltage channel incorporates a low-impedance output buffer that drives up to 5 mA of current.

The SCXI-1124 runs with NI-DAQmx driver software that is compatible with packages/application development environments (ades) such as LabVIEW, LabWindows/CVI or Measurement Studio.

The SCXI-1124 is digitally processed through SCXIbus, so a single DAQ gadget can control multiple NI SCXI-1124 modules. In multiplex serial mode, a DAQ gadget uses the serial computerized information convention to control at least one SCXI-1124 module via SCXIbus. This activity method uses up to five computerized I/O lines, the module DAQ gadget. The unit comes with a 48-pin DIN C male front connector and a 50-pin male ribbon cable rear connector. NI devices measure 1.2 x 6.8 x 8.0 inches. In the physical dimension.
