NI-9234 I/O 连线或连接器。

尽管 NI 9234 模块具有较高的认证标准，当它与 NI USB-9162 外盒配合使用时，系统
满足的标准受各组件限制。详细信息见产品规范。
注意 该符号表明组件表面温度较高，触摸该组件可能导致受伤。
注意 电源未断开或处于非安全环境时，请勿断开 I/O 连线或连接器。
注意 电源未断开或处于非安全环境时，请勿卸除模块。
注意 NI USB-9234 未通过用于危险环境的认证。
如连接危险电压至模块，需采取下列防护措施。危险电压是指峰值电压高于
42.4 Vpk 的交流电压或高于 60 VDC 的直流电压。
注意 确保危险电压的连接由具有当地电气安全资质的专业人士完成。
注意 请勿将危险电压电路和人体可接触电路放置在同一模块内。
注意 确保连接至模块的设备和电路与人体接触有效隔离。
每套应用软件包和驱动程序都包括完成测量和控制测量设备的编程信息。
下列参考文档假定用户已安装 NI-DAQmx 8.8 或更高版本，如使用 NI 应用
软件，其版本应为 7.1 或更高。

如在 Measurement Studio 中使用 Visual C++、 Visual C#、
Visual Basic .NET 对 NI-DAQmx 支持的设备编程，可在 MAX 或
Visual Studio .NET 中打开 DAQ 助手，交互式地创建通道和任务。在
Measurement Studio 中，可根据任务或通道生成配置代码。关于生成
代码的详细信息，见 DAQ 助手帮助。或者在应用程序开发环境 (ADE) 中
使用 NI-DAQmx API 创建通道和任务。

Although the NI 9234 module has a high certification standard, when it is used in conjunction with the NI USB-9162 outer box, the system
The standards that can be met are limited by the components. See Product Specification for details.
Note that this symbol indicates that the surface temperature of the component is high and that touching the component may result in injury.
Caution Do not disconnect I/O cables or connectors when the power supply is not disconnected or in an unsafe environment.
Caution Do not remove the module when the power supply is not disconnected or in an unsafe environment.
Note that NI USB-9234 is not certified for use in hazardous environments.
If a dangerous voltage is connected to the module, the following precautions should be taken. Dangerous voltage means peak voltage is higher than
Ac voltage of 42.4 Vpk or DC voltage higher than 60 VDC.
Take care to ensure that hazardous voltage connections are made by professionals with local electrical safety qualifications.
Do not place the dangerous voltage circuit and the human body accessible circuit in the same module.
Take care to ensure that devices and circuits connected to the module are effectively isolated from human contact.
Each application package and driver includes programming information to complete the measurement and control the measurement device.
The following reference documents assume that you have Ni-DAQMX 8.8 or higher installed, if you are using NI applications
Software, whose version should be 7.1 or higher.

For example, Visual C++, Visual C#,
Visual Basic.NET for Ni-DAQMX-supported device programming, available at MAX or
Open the DAQ assistant in Visual Studio.NET to interactively create channels and tasks. in
In Measurement Studio, configuration code can be generated by task or channel. About generation
For details of the code, see DAQ Assistant Help. Or in an application development environment (ADE)
Create channels and tasks using the NI-DAQmx API.
