National Instruments SCXI-1339接线端子

National Instruments SCXI-1339（部件号：777687-39）是一款前置式T型接线盒。该 T型模块专为与 National Instruments SCXI-1129 多路复用器开关配合使用而设计。使用此 Terminal Block，用户可以将 SCXI-1129 配置为 2 线、双 4 x 32 矩阵。对于 色谱 柱 扩展， NI SCXI-1339 还 可以 通过 行 连接 接受 矩阵 扩展 电缆。将 SCXI 1339 与 SCXI-1129 配合使用可简化模拟信号的接线; 这种布置支持高电压和低电压电平。

该 T型块可以很容易地插入 SCXI-1129 上提供的前端连接器。为了提高安全性并保持 T形块牢固地固定到位，还提供了几个翼形螺钉。该型号允许的最大通道间和通道对地工作电压为 150 V。由于 NI SCXI-1339 是 I 级 测量 设备， 因此 只能 在 小于 或 等于 150 V 的 电压 下 使用 。但是，它经过测试可承受高达 800 V 的浪涌电压。此 Terminal Block 的安装和配置不需要任何额外的软件或硬件资源。

借助 SCXI-1339 可实现 4 x 32 矩阵，用户可控制双独立 4 x 32 矩阵。在这种配置中，用户可以通过 Terminal Block 或 HVAB 连接到行，而可以通过 Terminal Block 访问列。

National Instruments SCXI-1339 Wiring terminals

The National Instruments SCXI-1339 (Part number: 777687-39) is a front-mounted T-junction box. The T-module is designed for use with the National Instruments SCXI-1129 multiplexer switch. Using this Terminal Block, users can configure the SCXI-1129 as a 2-wire, dual 4 x 32 matrix. For column expansion, NI SCXI-1339 can also accept matrix expansion cables via row connections. The combination of SCXI 1339 and SCXI-1129 simplifies the wiring of analog signals; This arrangement supports both high and low voltage levels.

The T-block can be easily plugged into the front-end connector provided on the SCXI-1129. For added safety and to keep the T-block firmly in place, several wing screws are also provided. This model allows a maximum inter-channel and channel-to-ground operating voltage of 150 V. Because the NI SCXI-1339 is a Class I measuring device, it can only be used at a voltage of 150 V or less. However, it has been tested to withstand surge voltages up to 800 V. The installation and configuration of this Terminal Block does not require any additional software or hardware resources.

With the SCXI-1339, a 4 x 32 matrix can be realized, and the user can control two independent 4 x 32 matrices. In this configuration, a user can connect to a row through a Terminal Block or HVAB, while a column can be accessed through a Terminal Block.
