You must follow these guidelines to meet the shock and vibration
performance specifications stated in the device datasheet on
ni.com/manuals .
• Panel mount the system.
• Provide strain relief for the module by securing the cabling to
a supporting fixture no more than 8 cm (3 in.) away from the
opening of the connector backshell.
• Ensure that the supporting fixture for strain relief is stiff and
rigidly coupled to the chassis mounting surface.
• Ensure that you do not directionally bias the module when
applying strain relief.
Digital I/O Protection
The NI 9351 provides overcurrent and short-circuit protection for
each DO channel.
Caution Overvoltage and negative voltage conditions
can damage the NI 9351. Check the voltage
specifications for all devices that you connect to the
NI 9351.
