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.
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...

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.
