The NI 9265 has four analog output channels, AO. Each channel
has a common terminal, COM, that is internally connected to the
isolated ground reference of the module. The 9265 also has a
terminal for an external power supply, V
sup
, and an external power
supply common terminal, Power Supply COM.
Each AO channel has a digital-to-analog converter (DAC) that
produces a current signal. Each channel also has overvoltage and
short-circuit protection. Refer to the
Specifications section for
more information about the overvoltage and short-circuit
protection. Refer to Figure 3 for an illustration of the output
circuitry for one channel of the NI 9265.
You can connect a load to each channel of the NI 9265. Connect the
positive lead of the load to the AO terminal. Connect the ground of
the load to the corresponding COM terminal. Refer to Figure 3 for
an illustration of how to connect a load to the NI 9265.
