National Instruments SCXI-1308 电流输入接线端子

SCXI-1308（部件号：777687-08）32通道接线端子采用78个螺丝端子屏蔽，可连接到以下模块：SCXI-1102/B/C和SCXI-1100模块。 有 32 个 249 Ω精密电阻器，可在测量 0 至 20 mA 和 4 至 20 mA 过程电流源时将电流更改为电压。然后，与SCXI-1308一起使用的SCXI模块测量电压，使数据采集板能够获得电压。32对螺丝端子可以连接到SCXI模块的32个差分输入端。一对端子可以链接到模块的机箱接地引脚。三个端子与SCXI模块OUTPUT和AOREF引脚以及SCXIbus保护装置相连。其余的终端将被保存以备将来使用。

要安排和操作NI SCXI 1308接线端子，需要几个项目：安装指南、SCXI机箱、SCXI-1102/B/C或SCXI-1100模块、1号和2号飞利浦螺丝刀，以及1/10英寸和1/4英寸平头螺丝刀。安装过程包括将接线端子连接到SCXI模块的前连接器，然后拧紧SCXI-1308背面的底部和顶部翼形螺钉，以确保其牢固。

SCXI 1308电流输入端子可以将电流转换为电压，然后测量电压，数据采集板获取电压。针对 4 至 20 mA 电流源测得的电压将介于 0.996 至 4.98 VDC 之间。NI SCXI-1308 能够 测量 电流 和 电压 源。在测量电压信号时，用户应移除该特定输入通道的电流环路电阻。它具有高达 30 Vrms 和 42.4 Vpeak 或 60 VDC 的通道间和通道对地电压。NI 设备 的 工作 温度 范围 为 0° 至 50° C， 存储 温度 范围 为 –20° 至 70° C， 非冷凝 相对湿度 范围 为 5% 至 90%。

【英文介绍】

National Instruments SCXI-1308 Current input terminal

The SCXI-1308 (Part number: 777687-08) 32 channel terminal blocks are shielded with 78 screw terminals and can be connected to the following modules: SCXI-1102/B/C and SCXI-1100 modules. There are 32 249Ω precision resistors that change current to voltage when measuring 0 to 20 mA and 4 to 20 mA process current sources. The SCXI module used with the SCXI-1308 then measures the voltage, enabling the data acquisition board to obtain the voltage. 32 pairs of screw terminals can be connected to the 32 differential inputs of the SCXI module. A pair of terminals can be linked to the chassis grounding pin of the module. The three terminals are connected to the SCXI module OUTPUT and AOREF pins and the SCXIbus protection device. The remaining terminals will be saved for future use.

To arrange and operate the NI SCXI 1308 terminal blocks, several items are required: installation guide, SCXI chassis, SCXI-1102/B/C or SCXI-1100 modules, No. 1 and No. 2 Philips screwdrivers, and 1/10 inch and 1/4 inch flat head screwdrivers. The installation process involves connecting the terminal to the front connector of the SCXI module, then tightening the bottom and top wing screws on the back of the SCXI-1308 to ensure it is secure.

The SCXI 1308 current input terminal converts the current to voltage, then measures the voltage, and the data acquisition board obtains the voltage. Voltages measured against 4 to 20 mA current sources will range from 0.996 to 4.98 VDC. The NI SCXI-1308 is capable of measuring current and voltage sources. When measuring a voltage signal, the user should remove the current loop resistance for that particular input channel. It has interchannel and channel-to-ground voltages up to 30 Vrms and 42.4Vpeak or 60 VDC. The operating temperature range of NI devices is 0° to 50° C, the storage temperature range is -20 ° to 70° C, and the non-condensing relative humidity range is 5% to 90%.
