National Instruments SCXI-1313 高压衰减器接线端子

SCXI-1313（部件号：777687-13）是一款屏蔽式接线端子，设计用于SCXI-1125模块。 SCXI 1313上的每个通道都有一个精密的100：1电阻分压器，用户可以使用SCXI-1125测量最大300 VRMS或±300 VDC的电压。对于低压测量应用，用户可以单独旁路分压器。NI SCXI-1313 接线端子上有 18 个螺丝端子，可实现简单的信号连接。一对螺丝端子连接到SCXI-1125模块机箱接地。其他 8 对螺丝端子将信号连接到 8 个模拟输入。

用户可以通过在Measurement & Automation Explorer中更改接线端子的标准配置设置来启用或禁用NI SCXI 1313上的衰减器。另一种选择是用户在其应用程序中更改输入限制范围。如果用户使用虚拟通道，则使用虚拟通道配置器中配置的输入限值来正确指定衰减电路。

接线端子使用NIDAQmx驱动程序软件运行，该软件与软件包或LabVIEW或LabWindows/CVI等应用程序开发环境兼容。该设备可以使用Measurement & Automation Explorer （MAX）工具进行配置。

SCXI-1313接线端子具有温度传感器，可在0至50°C的温度范围内输出1.91至0.65 V的电压。 如果用户正在使用LabVIEW，则可以利用转换热敏电阻读数。用户应利用许多样品来获得最精确的读数。嘈杂的条件需要更多的样品来确保精度。

【英文介绍】

National Instruments SCXI-1313 High voltage attenuator terminal

The SCXI-1313 (Part number: 777687-13) is a shielded terminal designed for use in the SCXI-1125 module. Each channel on the SCXI 1313 has a precision 100:1 resistance divider that allows users to measure voltages up to 300 VRMS or ±300 VDC with the SCXI-1125. For low voltage measurement applications, the user can bypass the voltage divider separately. The NI SCXI-1313 terminal has 18 screw terminals for simple signal connection. A pair of screw terminals are connected to the SCXI-1125 module chassis grounding. The other 8 pairs of screw terminals connect the signal to 8 analog inputs.

The user can enable or disable the attenuator on the NI SCXI 1313 by changing the standard configuration Settings of the terminal in the Measurement & Automation Explorer. Another option is for the user to change the range of input limits in their application. If the user uses a virtual channel, the input limits configured in the virtual channel configurator are used to correctly specify the attenuation circuit.

Terminals are run using NIDAQmx driver software, which is compatible with software packages or application development environments such as LabVIEW or LabWindows/CVI. The device can be configured using the Measurement & Automation Explorer (MAX) tool.

The SCXI-1313 terminal has a temperature sensor that outputs voltages from 1.91 to 0.65 V over a temperature range of 0 to 50°C. If the user is using LabVIEW, it is possible to convert the thermistor reading. Users should utilize many samples to obtain the most accurate reading. Noisy conditions require more samples to ensure accuracy.
