National Instruments SCXI-1306接线端子

NI SCXI-1306（部件号：779698-01）旨在与SCXI-1503 RTD模块一起使用。该接线端子采用屏蔽设计，可实现快速、简单的信号连接，并可轻松安装到模块前部。SCXI 1306 有 16 对用于差分输入信号的螺丝端子和 16 对用于电流激励信号的附加螺丝端子。

NI SCXI-1306 接线端子可对传感器（包括 RTD 和热敏电阻）进行 2 线、3 线和 4 线电阻测量。每个通道都可以配置为电压或电阻测量。每个通道有两个开关，可用于选择测量类型。此外，16 个差分模拟通道可用于完成浮动和接地电压测量。热电偶测量是浮动测量的特征。对于浮动或接地电压测量，用户可以将电压源连接到模拟输入螺丝端子。然后，用户可以根据他们正在测量的信号类型修改开关位置。当用户测量浮动信号时，他们可以将负输入连接到SCXI-1503 RTD模块的内部接地。

NI SCXI-1306 接线端子 的 一个 优点 是 集成 了 温度 传感器。此功能可用于热电偶冷端补偿。为确保精确的冷端补偿，用户不得将SCXI机箱保持在任何极端温差附近。NI 还 建议 对 大量 样品 进行 平均 ， 以 获得 精确 的 读数。

National Instruments SCXI-1306 Wiring terminals

The NI SCXI-1306 (Part number: 779698-01) is intended for use with the SCXI-1503 RTD module. The terminal is designed with a shielded design for fast, simple signal connection and can be easily installed to the front of the module. The SCXI 1306 has 16 pairs of screw terminals for differential input signals and 16 pairs of additional screw terminals for current excitation signals.

The NI SCXI-1306 terminal provides 2-wire, 3-wire, and 4-wire resistance measurements to sensors, including RTDS and thermistors. Each channel can be configured for voltage or resistance measurement. Each channel has two switches that can be used to select the type of measurement. In addition, 16 differential analog channels can be used to complete floating and ground voltage measurements. Thermocouple measurement is a characteristic of floating measurement. For floating or ground voltage measurements, the user can connect the voltage source to the analog input screw terminal. The user can then modify the switch position based on the type of signal they are measuring. When the user measures the floating signal, they can connect the negative input to the internal grounding of the SCXI-1503 RTD module.

One advantage of the NI SCXI-1306 terminals is the integrated temperature sensor. This function can be used for thermocouple cold end compensation. To ensure accurate cold end compensation, users must not hold the SCXI chassis near any extreme temperature difference. NI also recommends averaging a large number of samples to get an accurate reading.
