Hazardous Voltage This icon denotes a warning

advising you to take precautions to avoid electrical
shock.

Safety Guidelines for Hazardous Voltages

If hazardous voltages are connected to the device, take the
following precautions. A hazardous voltage is a voltage greater
than 42.4 Vpk voltage or 60 V DC to earth ground.

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 Ensure that devices and circuits connected to

the module are properly insulated from human contact.

Caution When module terminals are hazardous

voltage LIVE (>42.4 Vpk/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.

electrical supply system that powers equipment. This category is
for measurements of voltages from specially protected secondary
circuits. Such voltage measurements include signal levels, special
equipment, limited-energy parts of equipment, circuits powered
by regulated low-voltage sources, and electronics.

Caution Do not connect the NI 9269 to signals or use

for measurements within Measurement Categories II,

Note Measurement Categories CAT I and CAT O are

equivalent. These test and measurement circuits are not
intended for direct connection to the MAINS building
installations of Measurement Categories CAT II,
CAT III, or CAT IV.

Measurement Category II is for measurements performed on
circuits directly connected to the electrical distribution system.
This category refers to local-level electrical distribution, such as
that provided by a standard wall outlet, for example, 115 V for
U.S. or 230 V for Europe.

Caution Do not connect the NI 9269 to signals or use

for measurements within Measurement Categories III
or IV.

Safety Guidelines for Hazardous Locations

The NI 9269 is suitable for use in Class I, Division 2, Groups A,
B, C, D, T4 hazardous locations; Class I, Zone 2, AEx nA IIC T4
Gc and Ex nA IIC T4 Gc hazardous locations; and nonhazardous
locations only. Follow these guidelines if you are installing the
NI 9269 in a potentially explosive environment. Not following
these guidelines may result in serious injury or death.

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.

NI 9269 Connection Guidelines

• Make sure that devices you connect to the NI 9269 are
compatible with the module specifications.

• You must use 2-wire ferrules to create a secure connection
when connecting more than one wire to a single terminal on
the NI 9269.

High-Vibration Application Connections

If your application is subject to high vibration, NI recommends
that you follow these guidelines to protect connections to the
NI 9269:

• Use ferrules to terminate wires to the detachable connector.

• Use the NI 9971 connector backshell kit.

Overvoltage Protection

The NI 9269 provides overvoltage protection for each channel.

Note Refer to the device datasheet on ni.com/manuals

for more information about overvoltage protection.

16 | ni.com | NI 9269 Getting Started Guide

Increasing Output Voltage Range

Each channel of the NI 9269 has a nominal output 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
AO<1, 2, 3> is limited to ±10 mA total or ±3.33 mA each.

If you want to increase the nominal output voltage range, you can
stack up to four output channels for a maximum of ±40 V
nominal. For example, if you want two channels with a nominal
output voltage range of ±20 V each, connect AO<0, 1> and
AO<2, 3>. The output current of the stacked channels flows
across two channels, limiting the total output current to ±10 mA.

Load

Stacking 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.
