National Instruments SCXI-1127 矩阵/多路复用器开关模块

SCXI-1127（部件号：776572-27）是一款高压矩阵/多路复用器模块，提供多种配置：1 x 32、2线多路复用器、2 x 16、2线多路复用器和4 4 x 8、2线多路复用器。使用特殊接线端子可以进行更多配置，例如 4 x 8 2 线或 1 x 32 2 线矩阵。通过使用软件可配置开关，该模块还可以用作 1 x 64 1 线或 1 x 64 4 线多路复用器。 NI SCXI-1127 非常 适合 低 电压 和 高 电压。对于低电压测量，该矩阵/多路复用器开关模块利用具有极低热偏移的继电器来保证精确测量。另一方面，对于高压测量，该模块可以在 200 mA 负载下承受高达 250 Vrms 的信号，在 1 A 负载下承受 30 VDC 的信号。SCXI

1127 使用 NI- SWITCH 驱动 软件 运行 ， 该 软件 支持 LabVIEW、 Measurement Studio、 Visual Basic、 Microsoft C 和 C++ 等 应用 开发 环境 （ADE）。可以使用Measurement & Automation Explorer工具对设备进行配置。

NI SCXI-1127 具有 多功能 的 扫描 结构。用户可以任意扫描通道，并在一次扫描中具有多种输入模式，这在将多种传感器类型连接到单个模块时很有帮助。 SCXI-1127有两种扫描方式：软件扫描和硬件定时扫描。软件扫描允许通过软件选择通道。此过程不需要触发器连接。此外，软件扫描无法提供硬件定时扫描所提供的时间精确度。硬件定时扫描使测量设备（如数字万用表）能够通过数字触发信号与NI SCXI-1127进行通信。硬件定时扫描也有两种类型：同步扫描和握手。同步扫描只需要从设备到多路复用器的单个信号，但握手需要从多路复用器连接到设备的另一个信号。SCXI-1127 重 1 磅，尺寸为：1.2 x 6.8 x 7.8 英寸。

【英文介绍】

National Instruments SCXI-1127 Matrix/multiplexer switch module

The SCXI-1127 (Part number: 776572-27) is a high-voltage matrix/multiplexer module available in a variety of configurations: 1 x 32, 2-wire multiplexer, 2 x 16, 2-wire multiplexer, and 4 4 x 8, 2-wire multiplexer. More configurations can be made using special terminals, such as a 4 x 8 2-wire or 1 x 32 2-wire matrix. By using software configurable switches, the module can also be used as a 1 x 64 1-wire or 1 x 64 4-wire multiplexer. The NI SCXI-1127 is ideal for both low and high voltages. For low voltage measurements, the matrix/multiplexer switching module utilizes relays with extremely low thermal offset to guarantee accurate measurements. For high voltage measurements, on the other hand, the module can withstand signals up to 250 Vrms at 200 mA loads and 30 VDC at 1 A loads. SCXI

The 1127 runs with NI-SWITCH driver software that supports application development environments (ades) such as LabVIEW, Measurement Studio, Visual Basic, Microsoft C, and C++. The device can be configured using the Measurement & Automation Explorer tool.

NI SCXI-1127 has a versatile scanning structure. Users can scan any channel and have multiple input modes in a single scan, which is helpful when connecting multiple sensor types to a single module. SCXI-1127 has two scanning modes: software scanning and hardware periodic scanning. Software scanning allows channels to be selected by software. This procedure does not require a trigger connection. In addition, software scanning does not provide the time accuracy that hardware timing scanning provides. Hardware timing scanning enables measuring devices, such as digital multimeters, to communicate with the NI SCXI-1127 via digital trigger signals. There are also two types of hardware timing scan: synchronous scan and handshake. A synchronous scan requires only a single signal from the device to the multiplexer, but a handshake requires another signal from the multiplexer to be connected to the device. The SCXI-1127 weighs 1 pound and measures 1.2 x 6.8 x 7.8 inches.
