NI 9269 Connection Guidelines
■ Make sure that devices you connect to the NI-9269 are compatible with the
module specifications.
■ You must use 2-wire ferrules to create a secure connection when connecting
more than one wire to a single terminal on the NI-9269.
High-Vibration Application Connections
If your application is subject to high vibration, NI recommends that you follow these
guidelines to protect connections to the NI-9269:
■Use ferrules to terminate wires to the detachable connector.
■Use the NI 9971 connector backshell kit.
Overvoltage Protection
The NI-9269 provides overvoltage protection for each channel.
Note Refer to the NI-9269 Specifications on ni.com/manuals for more
information about overvoltage protection.

Increasing Output Voltage Range
Each channel of the NI 9269 has a nominal output range of ±10 V and can drive up to
±10 mA of current. The total output current of all channels is limited to ±20 mA. For
example, if the output current of AO0 is ±10 mA, the output current of AO<1, 2, 3> is
limited to ±10 mA total or ±3.33 mA each.
If you want to increase the nominal output voltage range, you can stack up to four
output channels for a maximum of ±40 V nominal. For example, if you want two
channels with a nominal output voltage range of ±20 V each, connect AO<0, 1> and
AO<2, 3>. The output current of the stacked channels flows across two channels,
limiting the total output current to ±10 mA.

Load
Stacking more than four output channels of multiple NI 9269 modules violates the
electrical safety and overvoltage protection ratings.
Because the NI 9269 outputs can source and sink current, it is not possible to
increase the current drive by connecting output channels in parallel.
Note Refer to the device datasheet on ni.com/manuals for more
information about the overvoltage protection rating.
