SCXI频率输入模块

8通道频率输入模块 - 用于SCXI—SCXI‑1126是一款用于SCXI的隔离频率输入模块。 每个通道包括一个具有可编程输入范围、阈值、滞后和滤波的频率/电压转换电路。 该模块的输出电压复用到数据采集设备的单通道上，因此您可以在单次高速扫描操作中扫描和采集多个频率和模拟输入信号。

NI SCXI-1326（部件号：777687-26）是一款高压螺丝接线端子，支持连接到SCXI-1162、SCXI-1162HV、SCXI-1163和SCXI-1163R模块的前连接器。NI SCXI-1326 专为高压数字输入或数字输出应用而设计。该接线端子也非常适合具有大量通道的温度或电压应用。 NI SCXI-1326 是 一 款 屏蔽 接线端子， 可 快速、轻松地 连接 信号。SCXI 1326 的最大电压为 300 V，是 Cat II 型号。

NI SCXI 1326 有 48 个 螺丝 端子， 分布 在 8 组， 每 组 有 6 个 端子。每个组都与其他组分开。一组中的六个端子由以下端子组成：VCC、GND 和四个通道。终端的利用率基于模块。例如，SCXI-1326上的VCC端子不用于SCXI-1162HV或SCXI-1163R模块。此外，SCXI-1162上未使用GND端子。SCXI-1162上的VCC端子是电源/基准电压，而SCXI 1163上的电源5 V±0.5 V则以GND为基准。 GND是指SCXI-1162HV的接地参考、SCXI-1163的接地和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 frequency input module

8-channel Frequency Input Module - for SCXI - SCXI‑1126 is an isolated frequency input module for SCXI. Each channel includes a frequency/voltage conversion circuit with programmable input ranges, thresholds, lags, and filters. The module's output voltage is multiplexed onto a single channel of the data acquisition device, so you can scan and acquire multiple frequency and analog input signals in a single high-speed scan operation.

NI SCXI-1326 (Part number: 777687-26) is a high voltage screw terminal that supports front connectors to SCXI-1162, SCXI-1162HV, SCXI-1163, and SCXI-1163R modules. The NI SCXI-1326 is designed for high voltage digital input or digital output applications. The terminals are also ideal for temperature or voltage applications with a large number of channels. The NI SCXI-1326 is a shielded terminal for quick and easy signal connection. The SCXI 1326 has a maximum voltage of 300 V and is a Cat II model.

The NI SCXI 1326 has 48 screw terminals distributed in 8 sets of 6 terminals each. Each group is separated from the others. The six terminals in a set consist of the following terminals: VCC, GND, and four channels. Terminal utilization is based on module. For example, the VCC terminal on the SCXI-1326 is not used in the SCXI-1162HV or SCXI-1163R module. In addition, no GND terminals are used on SCXI-1162. The VCC terminal on the SCXI-1162 is the power supply/reference voltage, while the power supply 5 V±0.5 V on the SCXI 1163 is the GND reference. GND refers to the grounding reference of SCXI-1162HV, the grounding of SCXI-1163, and the common pole of SCXI-1163R. Finally, CHAN (x) is the digital input of SCXI-1162, the input signal of SCXI 1162HV, the digital output of SCXI 1163, and the relay input of the SCXI 1163R module.
