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.
