The NI 9224 outputs1 kS/s of data at the maximum sampling rate. Designed for both speed and accuracy, theNI 9224 is an effective general-purpose analog module because of its resolution, sample rate,and input ContentsAccessories NI 9939 Screw Terminal Connector Backshell Kit NI 9224 NI 9224 Getting Started GuideNI C Series OverviewNI provides more than 100 C Series modules for measurement, control, and communicationapplications.

2 C Series modules can connect to any sensor or bus and allow for high-accuracymeasurements that meet the demands of advanced data acquisition and control applications. Measurement-specific signal conditioning that connects to an array of sensors and signals Isolation options such as bank-to-bank, channel-to-channel, and channel-to-earth ground -40 C to 70 C temperature range to meet a variety of application and environmentalneeds Hot-swappableThe majority of C Series modules are supported in both CompactRIO and CompactDAQplatforms and you can move modules from one platform to the other with no combines an open-embedded architecturewith small size, extreme ruggedness, and C Seriesmodules in a platform powered by the NI LabVIEW reconfigurable I/O (RIO) architecture.

3 Each systemcontains an FPGA for custom timing, triggering, andprocessing with a wide array of available modular I/O tomeet any embedded application is a portable, rugged data acquisition platformthat integrates connectivity, data acquisition, and signalconditioning into modular I/O for directly interfacing to anysensor or signal.

Each AI channel provides an independent signal path and ADC, enabling you to sampleall channels ModesThe NI 9224 supports high resolution, medium resolution, high speed, and medium speedtiming modes. High resolution timing mode optimizes noise and rejects power linefrequencies. Medium resolution timing mode has a higher sample rate when compared withhigh resolution, and also rejects power line frequencies.

6 High speed timing mode optimizessample rate and signal bandwidth, whereas medium speed timing mode has lower noise whencompared to high speed timing 9224 SpecificationsThe following specifications are typical for the range -40 C to 70 C unless otherwise voltages are relative to the AI- signal on each channel unless otherwise Do not operate the NI 9224 in a manner not specified in this misuse can result in a hazard.
