NI SCXI-1160 （部件号 ： 776572-60 ） 通用 开关 模 块 具有 16 个 独立 SPDT C 型 机电 锁存 继电器， 具有 极低 的 导通 电阻 和 热 偏移。 该模块的继电器能够切换、路由和控制中级信号。 SCXI 1160 开关模块的最大开关 速率为每秒 50 次操作，完全可通过软件编程。 该模块的开关容量在 2 VRMS 时为 250 A，在 2 VDC 时为 30 A。

通用开关模块的工作原理是通过检测输入信号的高低电平来控制输出信号的开关状态。具体来说，开关量模块通常具有一个或多个输入引脚和一个或多个输出引脚。SCXI-1160 输入引脚用于接收外部的开关信号，而输出引脚用于控制外部设备的开关状态。

当外部开关信号为高电平时，输入引脚上的电压高于一定的阈值，SCXI-1160 开关量模块会将对应的输出引脚置为高电平，从而控制外部设备的开关状态为打开。反之，当外部开关信号为低电平时，输入引脚上的电压低于一定的阈值，开关量模块会将对应的输出引脚置为低电平，从而控制外部设备的开关状态为关闭。

开关量模块具有快速响应、高可靠性、简化电路设计等特点，SCXI-1160 广泛应用于各种自动控制系统中。例如，它可以用于检测和控制按钮、开关、传感器信号等，并通过控制继电器或其他开关设备来实现自动化控制。

总的来说，开关量模块的工作原理就是根据输入信号的高低电平来控制输出信号的开关状态，以实现对外部设备的控制。

The NI SCXI-1160 (Part number: 776572-60) universal switch module features 16 separate SPDT Type C electromechanical latch relays with extremely low on-resistance and thermal offset. The module’s relays are capable of switching, routing and controlling intermediate signals. The SCXI 1160 switch module has a maximum switching rate of 50 operations per second and is fully software-programmable. The switching capacity of the module is 250 A at 2 VRMS and 30 A at 2 VDC.

The working principle of the universal switching module is to control the switching state of the output signal by detecting the high and low level of the input signal. Specifically, a switching module usually has one or more input pins and one or more output pins. The SCXI-1160 input pins are used to receive external switching signals, while the output pins are used to control the switching state of external devices.

When the external switching signal is at high level and the voltage on the input pin is higher than a certain threshold, the SCXI-1160 switching module will set the corresponding output pin to high level, thus controlling the switching state of the external device to open. On the contrary, when the external switching signal is low voltage, the voltage on the input pin is lower than a certain threshold, and the switching module will set the corresponding output pin to low level, thus controlling the switching state of the external device to off.

SCXI-1160 is widely used in various automatic control systems because of its fast response, high reliability and simplified circuit design. For example, it can be used to detect and control buttons, switches, sensor signals, etc., and to automate control by controlling relays or other switching devices.

In general, the working principle of the switching module is to control the switching state of the output signal according to the high and low level of the input signal to achieve the control of external devices.
