National Instruments SCXI-1304 AC/DC耦合接线端子

SCXI-1304（部件号：777687-04）是National Instruments的SCXI系列接线端子。该AC/DC耦合接线端子可与SCXI-1140、SCXI-1141/1142/1143、SCXI-1120/D和SCXI-1125模块一起使用。 除 AC/DC 耦合外，该型号还具有 BNC 连接器和信号接地参考，可为每个通道进行配置。NI SCXI-1304 上有 22 个 螺丝 端子， 可 轻松 连接 信号。用户可以使用八对螺丝端子将信号连接到八个模块输入，并使用一对连接到模块模拟接地。其他四个螺丝端子用于访问模块的数字接地和数字信号。对于SCXI-1140，这些信号是HOLDTRIG。但是，对于SCXI-1141/1142/1143，这些信号是OUTCLK和EXTCLK。

当NI SCXI 1304接线端子与SCXI-1120/D、SCXI-1125或SCXI-1126一起使用时，如果偏置电阻处于接合设置中，则通道隔离规范无效。 用户必须将电阻开关保持在开路或 G 接地设置，以便隔离保持有效。

NI SCXI-1304 能够 通过 开关 设置 将 每 个 通道 都 配置 为 交流 或 直流 耦合。每个通道都需要两个位于相同位置的开关，耦合电路才能精确工作。对于交流耦合，用户必须将两个开关指定为交流设置，该设置将单极高通滤波器置于正负通道输入的路径中。另一方面，对于直流耦合，用户必须将两个开关都设置到直流位置。这消除了信号路径中的滤波器，并将螺丝端子直接连接到模块输入端。

它建议的工作和存储温度范围分别为 0 至 50 °C 和 –20 至 70 °C，非冷凝相对湿度范围为 10% 至 90%。SCXI-1304的设计符合以下电气安全标准：IEC 61010-1、EN 61010-1、UL 3111-1、UL 61010B-1和CAN/CSA C22.2 No. 1010.1。

National Instruments SCXI-1302 straight-through terminal

NI SCXI-1302 (Part number: 777687-02) is a member of the SCXI family manufactured by NI. The SCXI-1302 is a 50-screw front terminal. It is highly recommended to use this model with the SCXI-1180 feedthrough plate. The terminal is installed on the front of the SCXI module. Screw terminals allow for simple signal connections to feed-through plates.

The SCXI-1302 has a number of beneficial features that help make signal connectivity as seamless as possible. The SCXI 1302 features a shielded design to ensure fast and reliable signal connections. The terminals also have rack mount and DIN rail mount options. This model also has a stress relief clamp to ensure the signal line is firmly in place. The National Instruments SCXI 1302 straight-through terminals are connected directly to the sensor at the screw terminal in a fully shielded housing.

To set up the SCXI-1302, several items are required, including: installation guide, wire insulation strippers, wire cutters, long nose pliers, 1/4 inch. And 1/8 of an inch. Flat-head screwdriver, No. 1 and No. 2 Philips screwdrivers, SCXI chassis, and SCXI-1180 Feedthrough plate. The NI SCXI 1302 has a 26-16 AWG maximum field line gauge and DC coupling. The transition frequency is 0.16 Hz 1 pole RC. The DC rejection capability of the terminal is ±50 VDC.

The SCXI-1302 runs with NIDAQmx driver software, which can be programmed using a software package or application development environment (ADE), such as LabVIEW, LabWindows/CVI, ComponentWorks, etc. The device can be configured using the Measurement & Automation Explorer (MAX) tool. NI equipment is designed to comply with the following electrical safety standards: IEC 61010-1, EN 61010-1, UL 61010-1 and CSA 61010-1.
