Connect the positive lead of the load to the AO terminal. Connect the
ground of the load to an AO GND terminal. Figure 22 shows a load
connected to one analog input channel.

Load Connected to One Analog Input Channel
Integrated 24 V Digital Input
(NI sbRIO-964
x
/9642XT Only)
Connector J6 of the NI sbRIO-964
x
/9642XT provides connections for
32 simultaneously sampled digital input channels. Each channel has
one pin, DI, to which you can connect a digital input signal. The remaining
two pins of J6 are the ground reference pins, D GND. Refer to the
Other Connectors on the NI sbRIO Device
section for a pinout of
connector J6.
The integrated digital input of the NI sbRIO device is similar to that of the
NI 9425, but there is no isolation. The 24 V digital input channels are
sinking inputs, meaning that when the device drives a current or applies a
voltage to the DI pin, the pin provides a path to D GND. D GND is the
current return path for sourcing digital input devices. The NI sbRIO-964
x
/
9642XT internally limits current signals connected to DI. For more
information about input current protection, refer to the
section.
You can connect 2-, 3-, and 4-wire sourcing-output
devices to the
NI sbRIO-964
x
/9642XT. A sourcing-output device drives current or
applies voltage to the DI pin. An example of a sourcing-output device is an
open collector PNP.
