Page 3: Safety Guidelines For Hazardous Voltages
Safety Guidelines Operate the NI 9269 only as described in these operating instructions. This icon denotes that the component may be Hot Surface hot. Touching this component may result in bodily injury. Safety Guidelines for Hazardous Voltages If hazardous voltages are connected to the module, take the following precautions. - Page 4 LIVE (>42.4 V /60 VDC), you must ensure that devices and circuits connected to the module are properly insulated from human contact. You must use the NI 9971 connector backshell kit to ensure that the terminals are not accessible. Figure 1 shows the NI 9971 connector backshell.

Page 8: Connecting The Ni 9269
Connecting the NI 9269 The NI 9269 has four 2-terminal detachable screw-terminal connectors that provide connections for 4 analog output channels. AO0+ AO0– AO1+ AO1– AO2+ AO2– AO3+ AO3– Figure 2. NI 9269 Terminal Assignments NI 9269 Operating Instructions and Specifications... - Page 9 You can connect a load to each channel of the NI 9269. Connect the positive lead of the load to the AO+ terminal. Connect the ground of the load to the corresponding AO– terminal. Refer to Figure 3 for an illustration of how to connect a load to the NI 9269.

Page 11: Wiring For High-Vibration Applications
If an application is subject to high vibration, National Instruments recommends that you either use ferrules to terminate wires to the detachable screw-terminal connector or use the NI 9971 backshell kit to protect the connections. Refer to Figure 5 for an illustration of using ferrules. -
Page 12: Increasing Output Voltage Range
Increasing Output Voltage Range Each channel of the NI 9269 has a nominal output voltage 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... - Page 13 Cascading 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.
