Caution Do not disconnect I/O-side wires or connectors
unless power has been switched off or the area is known
to be nonhazardous.
Caution Do not remove modules unless power has been
switched off or the area is known to be nonhazardous.
Caution Substitution of components may impair
suitability for Class I, Division 2.
Caution For Zone 2 applications, install the
CompactRIO system in an enclosure rated to at least
IP 54 as defined by IEC 60529 and EN 60529.
Special Conditions for Safe Use in Europe
This equipment has been evaluated as EEx nC IIC T4 equipment
under DEMKO Certificate No. 03 ATEX 0324020X. Each module

Safety Guidelines for Hazardous Voltages
If hazardous voltages are connected to the module, take the
following precautions. A hazardous voltage is a voltage greater
than 42.4 V
cRIO-9263 Operating Instructions 4 ni.com
or 60 VDC to earth ground.
peak
Caution Ensure that hazardous voltage wiring is
performed only by qualified personnel adhering to local
electrical standards.
Caution Do not mix hazardous voltage circuits and
human-accessible circuits on the same module.
Caution Make sure that devices and circuits connected to
the module are properly insulated from human contact.
Caution When module terminals are live with hazardous
voltages, make sure that the terminals are not accessible.
You can use the cRIO-9932 connector kit or put the
CompactRIO chassis in a suitably rated enclosure.

Wiring the cRIO-9263
The cRIO-9263 has a 10-terminal, detachable screw-terminal
connector that provides connections for four analog output
channels. Each channel has a terminal to which you can connect
the positive lead of a voltage signal, AO. The cRIO-9263 also has
common terminals, COM, that are internally connected to the
isolated ground reference of the module. Refer to Table 1 for the
terminal assignments for each channel.

Connecting a Load to the cRIO-9263
You can connect loads to the cRIO-9263. Connect the positive lead
of the load to the AO terminal. Connect the ground of the load to a
COM terminal.

cRIO-9263 Circuitry
The cRIO-9263 channels share a common ground that is isolated
from the other modules in the CompactRIO system. Each channel
has a digital-to-analog converter (DAC) that produces a voltage
signal. You must write binary values to the analog output channels.
Refer to the CompactRIO Bookshelf for more information about
converting and calibrating cRIO-9263 output values in software.

Each channel also has overvoltage and short-circuit protection.
For more information about the overvoltage and short-circuit
protection, refer to the Specifications section.

Sleep Mode
You can enable sleep mode for the CompactRIO system in
software. Typically, when a system is in sleep mode, you cannot
communicate with the modules. In sleep mode, the system
minimizes power consumption. The system thermal dissipation
may decrease. Refer to the Specifications section for more
information about power consumption and thermal dissipation.
Refer to the CompactRIO Bookshelf for more information about
enabling sleep mode in software.
