Safety Guidelines for Hazardous Voltages

Yo u can connect hazardous voltages only to the NI 9205 with
spring terminal. Do not connect hazardous voltages to the NI 9205
with DSUB.

If hazardous voltages are connected to the module, take the
following precautions. A hazardous voltage is a voltage greater
than 42.4 Vpk or 60 VDC 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 Make sure that devices and circuits connected to

the module are properly insulated from human contact.

© National Instruments Corp. 3 NI 9205 Operating Instructions and Specifications

Caution When module terminals are hazardous voltage

LIVE (>42.4V

/60 VDC), you must ensure that devices

pk

and circuits connected to the module are properly
insulated from human contact. You must use the NI 9940
connector backshell kit to ensure that the terminals are
not accessible. Figure 1 shows the NI 9940 connector
backshell.

Note Yo u can use the NI 9940 connector backshell only

with the NI 9205 with spring terminal.

Figure 2. NI 9205 Terminal and Pin Assignments

© National Instruments Corp. 7 NI 9205 Operating Instructions and Specifications

The NI 9205 provides connections for the 32 single-ended or
16 differential analog input channels, as well as one digital input
channel, one digital output channel, COM, and AI SENSE.

Note The digital output channel is supported only in

CompactRIO systems.

The NI 9205 with spring terminal has a 36-terminal detachable
spring-terminal connector, and the NI 9205 with DSUB has a
37-pin DSUB connector. Each analog input channel has an
AI terminal or pin to which you can connect an analog output
device. The NI 9205 is capable of an aggregate sampling rate of
250 kS/s. The NI 9205 also supports triggering. Refer to the
software help for information about input trigger modes.

The NI 9205 channels share a common ground that is isolated
from the other modules in the system. All channels share a
programmable gain instrumentation amplifier and are multiplexed
to an ADC. Each channel also has

±30 V overvoltage protection.

For more information about overvoltage protection, refer to the

Specifications section. Refer to Figure 3 for an illustration of the

input circuitry for one analog input channel on the NI 9205.

Connecting Wires to the NI 9205 Spring-Terminal Connector

Use a flathead screwdriver with a blade smaller than 2.3 × 1.0 mm
(0.09 × 0.04 in.) to connect wires to the detachable spring-terminal
connector. Insert the screwdriver into a spring clamp activation slot
and press a wire into the corresponding connector terminal, then
remove the screwdriver to clamp the wire into the terminal.
Refer to the Specifications section for more information about
spring-terminal wiring. Refer to Figure 4 for an illustration of
connecting wires to the NI 9205 with spring terminal.

Wiring for High-Vibration Applications

If an application is subject to high vibration, National Instruments
recommends that you use a backshell kit or shielded cable to
protect the connections. For the NI 9205 with spring terminal, use
the NI 9940 backshell to protect the connections. For the NI 9205
with DSUB, use a 37-pin shielded cable or the NI 9933 backshell
to protect the connections. Refer to Figure 1 for an illustration of
the NI 9940 connector backshell. Refer to Figure 5 for an
illustration of the NI 9933 connector backshell.

Connecting Devices to the NI 9205

Yo u can connect the NI 9205 directly to a variety of devices and
other signal sources. Make sure the devices you connect to the
NI 9205 are compatible with the input specifications of the
module. Refer to the Specifications section for more information
about the input specifications.

When connecting various sources to the NI 9205, you can use
differential, single-ended, or a combination of differential and
single-ended connections. Refer to Figures 6, 7, and 8 for
diagrams of each connection type.

© National Instruments Corp. 11 NI 9205 Operating Instructions and Specifications

Differential Measurements

Yo u can use a differential measurement configuration to attain
more accurate measurements and less noise. A differential
measurement configuration requires two inputs for each
measurement, thus reducing the number of available channels on
the NI 9205 to 16. Table 1 shows the signal pairs that are valid for
differential connection configurations with the NI 9205.

ADC

NI 9205

Note If you leave COM unconnected, the signals float

outside the working input range of the NI 9205. This may
result in unreliable measurements because there is no way
to ensure that the input signal is within 10 V of COM.

Non-Referenced, Single-Ended (NRSE) Measurements

Yo u can use an NRSE measurement configuration to take
measurements on all 32 channels while reducing noise more
effectively than with an RSE connection configuration. This
configuration provides remote sense for the negative (–) input of
the PGIA that is shared by all channels configured for NRSE mode.
The behavior of this configuration is similar to the behavior of RSE
connections, but it provides improved noise rejection. Refer to
Figure 8 for an illustration of connecting a device to the NI 9205
using NRSE connections.

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.

NI 9205 Operating Instructions and Specifications 16 ni.com

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.
