Each channel of the NI 9263E has an AO terminal and a common
terminal, COM, and there is an additional COM terminal at the
bottom of the connector. All of the COM terminals are internally
connected to the isolated ground reference of the module. You can
connect a load to each channel of the NI 9263E. Connect the
positive lead of the load to the AO terminal, and the ground of the
load to the corresponding COM terminal. Refer to Figure 3 for an
illustration of connecting a load to the NI 9263E.
Figure 3. Connecting a Load to the NI 9263E
Note You must use 2-wire ferrules to create a secure
connection when connecting more than one wire to a
single terminal on the NI 9263E.

Each channel has a digital-to-analog converter (DAC) that
produces a voltage 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 4 for an illustration of the output
circuitry for one channel of the NI 9263E.

documentation.
Sleep Mode
This module supports a low-power sleep mode. Support for sleep
mode at the system level depends on the chassis that the module is
plugged into. Refer to the chassis manual for information about
support for sleep mode. If the chassis supports sleep mode, refer to
the software help for information about enabling sleep mode. Visit
ni.com/info and enter cseriesdoc for information about
C Series documentation.
Typically, when a system is in sleep mode, you cannot
communicate with the modules. In sleep mode, the system
consumes minimal power and may dissipate less heat than it does
in normal mode. Refer to the Specifications section for more
information about power consumption and thermal dissipation.
