这镍SCXI-1326(零件号:777687-26)是一个高压螺丝端子板带有连接到SCXI-1162、SCXI-1162HV、SCXI-1163和SCXI-1163R模块前连接器的支架。这国家仪器公司SCXI-1326设计用于高压数字输入或数字输出应用。这接线盒也非常适合具有大量通道的温度或电压应用。这镍SCXI-1326是屏蔽的接线盒，可实现快速、便捷的信号连接。这SCXI 1326最大电压为300 V，为Cat II型号。

这倪SCXI 1326有48个螺丝端子，分为八组，每组六个端子。每个群体都与其他群体相分离。一组中的六个终端由以下终端组成:VCC、GND和四个通道。终端的使用基于模块。例如，VCC码头SCXI-1326不适用于SCXI-1162HV或SCXI-1163R模块。此外，SCXI-1162上没有使用GND终端。SCXI-1162上的VCC端子是电源/参考电压，而SCXI 1163上的电源为5V±0.5V，以GND为参考。GND是指SCXI-1162HV的接地参考、SCXI-1163的接地以及SCXI-1163R的公共极。最后，CHAN(x)是SCXI-1162的数字输入、SCXI 1162HV的输入信号、SCXI 1163的数字输出和SCXI 1163R模块的继电器输入。

SCXI-1326

The NI SCXI-1326 (Part Number: 777687-26) is a High-Voltage Screw Terminal Block with supports to link to the SCXI-1162, SCXI-1162HV, SCXI-1163, and SCXI-1163R modules’ front connector. The National Instruments SCXI-1326 is designed for high-voltage digital input or digital output applications. This Terminal Block is also well-suited for temperature or voltage applications with a large quantity of channels. The NI SCXI-1326 is a shielded Terminal Block, which allows for swift, easy signal connections. The SCXI 1326 has a maximum voltage of 300 V and is a Cat II model.

The NI SCXI 1326 has 48 screw terminals positioned in eight groups, with six terminals in each group. Every group is separate from the others. The six terminals in a group are comprised of the following terminals: a VCC, GND, and four channels. The utilization of the terminals is based on the module. For example, the VCC terminals on the SCXI-1326 are not utilized with the SCXI-1162HV or the SCXI-1163R modules. In addition, the GND terminals are not utilized on the SCXI-1162. The VCC terminals on the SCXI-1162 are power/reference voltage, where as they are for the power supply 5 V ±0.5 V on the SCXI 1163, which is referenced to GND. GND refers to ground reference for the SCXI-1162HV, ground for the SCXI-1163, and common pole for the SCXI-1163R. Lastly, CHAN(x) is the digital input for the SCXI-1162, the input signal for the SCXI 1162HV, the digital output for the SCXI 1163, and the relay inputs for the SCXI 1163R module.

The following components are required to run the SCXI-1326:
