Overview
The NI 9205 is a C Series module for use with NI CompactDAQ and CompactRIO chassis. It features 32 single-ended or 16 differential analog inputs, 16-bit resolution, and a
maximum sample rate of 250 kS/s. Each channel has programmable input ranges of ±200 mV, ±1 V, ±5 V, and ±10 V. To protect against signal transients, the NI 9205 includes
up to 60 V of overvoltage protection between input channels and common (COM). In addition, the NI 9205 features a channel-to-earth ground double isolation barrier for safety,
noise immunity, and high common-mode voltage range. It is rated for 1,000 Vrms transient overvoltage protection.
You can choose from two connector options for the NI 9205: a 36-position spring-terminal connector for direct connectivity or a 37-position D-SUB connector.

Application and Technology
NI C Series Overview
NI C Series modules are designed to provide high-accuracy measurements to meet the demands of advanced DAQ and control applications. Each module contains
measurement-specific signal conditioning to connect to an array of sensors and signals, bank and channel-to-channel isolation options, and support for wide temperature ranges
to meet a variety of application and environmental needs all in a single rugged package. You can choose from more than 100 C Series modules for measurement, control, and
communication to connect your applications to any sensor on any bus.
Most C Series I/O modules work with both the NI CompactDAQ and CompactRIO platforms. The modules are identical, and you can move them from one platform to the other
with no modification.
NI CompactRIO Platform
Powered by the NI LabVIEW reconfigurable I/O (RIO) architecture, NI CompactRIO combines an open embedded architecture with small size, extreme ruggedness, and
hot-swappable industrial I/O modules. Each system contains an FPGA for custom timing, triggering, and processing with a wide array of modular I/O to meet any embedded
application requirement.
Configure Your Complete NI CompactRIO System
NI CompactDAQ Platform
2/9
www.ni.com
NI CompactDAQ is a portable, rugged data acquisition platform that integrates connectivity and signal conditioning into modular I/O to directly interface with any sensor or signal.
Using NI CompactDAQ with LabVIEW, you can easily customize how you acquire, analyze, present, and manage your measurement data. From research to development to
validation, NI provides programmable software, high-accuracy measurements, and local technical support to help ensure you meet your exact measurement application
requirements.

Support and Services
System Assurance Programs
NI system assurance programs are designed to make it even easier for you to own an NI system. These programs include configuration and deployment services for your NI PXI,
CompactRIO, or Compact FieldPoint system. The NI Basic System Assurance Program provides a simple integration test and ensures that your system is delivered completely
assembled in one box. When you configure your system with the NI Standard System Assurance Program, you can select from available NI system driver sets and application
development environments to create customized, reorderable software configurations. Your system arrives fully assembled and tested in one box with your software preinstalled.
When you order your system with the standard program, you also receive system-specific documentation including a bill of materials, an integration test report, a recommended
maintenance plan, and frequently asked question documents. Finally, the standard program reduces the total cost of owning an NI system by providing three years of warranty
coverage and calibration service. Use the online product advisors at ni.com/advisor to find a system assurance program to meet your needs.
Calibration
NI measurement hardware is calibrated to ensure measurement accuracy and verify that the device meets its published specifications. To ensure the ongoing accuracy of your

Absolute accuracy formulas
AbsoluteAccuracy = Reading · GainError + Range · OffsetError + NoiseUncertainty
GainError = ResidualGainError + GainTempco · TempChangeFromLastInternalCal + ReferenceTempco · TempChangeFromLastExternalCal
OffsetError = ResidualOffsetError + OffsetTempco · TempChangeFromLastInternalCal + INL_Error
NoiseUncertainty = (RandomNoise · 3) /√100 for a coverage factor of 3 σ and averaging 100 points.
Absolute accuracy at full scale on the analog input channels is determined using the following assumptions:
TempChangeFromLastExternalCal = 70 °C
TempChangeFromLastInternalCal = 1 °C
NumberOfReadings = 100
CoverageFactor = 3 σ
For example, on the 10 V range, the absolute accuracy at full scale is as follows:
GainError = 115 ppm + 11 ppm · 1 + 5 ppm · 70
GainError = 476 ppm
OffsetError = 20 ppm + 44 ppm · 1 + 76 ppm
OffsetError = 140 ppm
NoiseUncertainty = (240 μV · 3) /√100
Noise Uncertainty = 72 μV
AbsoluteAccuracy = 10 V · 476 ppm + 10 V · 140 ppm + 72 μV
AbsoluteAccuracy = 6,232 μV (rounds to 6,230 μV)
