More Channels in Fewer Slots
The NI 9220 analog input circuitry was designed to closely match the circuitry of the NI 9215. A single NI 9220 can, in most cases, replace four NI 9215 modules at a lower price per channel.
High-Channel-Count Analog Control
Combine the NI 9220 (16-channel, 100 kS/s simultaneous input) with the NI 9264 (16-channel, 25 kS/s simultaneous output) and a CompactRIO chassis for high-channel-count control systems with FPGA control loop rates at up to 25 kHz.
At the maximum sample rate, the NI 9220 outputs 3.2 MB/s of data. The ability to process and store large amounts of data varies based on the selected hardware. Below are some guidelines for streaming performance based on chassis selection.
NI CompactDAQ Streaming Performance
NI CompactDAQ and the NI-DAQmx driver are designed for waveform measurement over standard interfaces such as USB, Ethernet, and WiFi (802.11). The values below are a rough guideline for data bandwidth requirements. Actual system performance varies based on processor, bus, and software.
-USB NI CompactDAQ can transfer approximately 20 MB/s of data over the bus, and most multicore computers can handle streaming this to disk.
-Stand-alone NI CompactDAQ is rated to stream 24 MB/s of data to disk. This is 120 channels from NI 9220 modules running at 100 kS/s per channel.
-Multislot Ethernet NI CompactDAQ can transfer approximately 10 MB/s of data in ideal network conditions. This is 50 channels from NI 9220 modules running at 100 kS/s per channel.
NI CompactRIO Streaming Performance
The NI cRIO-9082 system and MXI-Express reconfigurable I/O (RIO) expansion chassis have the largest throughput available and are the recommended solutions for high-speed streaming to disk applications within the CompactRIO family. All CompactRIO chassis have a built-in FPGA that is programmable with NI LabVIEW and can be used to process or filter data before it is transferred to the host controller. Note that communication with the host controller is not a requirement for high-speed control systems because the control logic can often be fully implemented in the FPGA using LabVIEW.
-The NI cRIO-9081/82 can stream to disk a full chassis of NI 9220 modules running at the maximum 100 kS/s per channel rate.
-MXI-Express expansion chassis have a throughput of approximately 200 MB/s, so 1,000 channels of NI 9220 data can stream over a single connection. This connection can be a daisy chain of multiple chassis that is connected to an NI cRIO-9082 or a PXI Express chassis for maximum streaming performance.
-The NI cRIO-9022 embedded real-time controller can stream a little more than 6 MB/s to disk. For direct streaming applications, this chassis can store approximately 30 NI 9220 channels running at the maximum sample rate.
Create a complete system with the NI 9220 and its accessories. However, the NI 9220 is compatible with multiple C Series Platforms, NI CompactDAQ and CompactRIO. Please review the comparison information below and select a platform to begin configuring your system.
Laboratory - 30 g shock and 0.3 grms operational vibration
Field Work - 50 g shock (Class I, Div 2 for Hazardous Locations)
The chassis provides rugged, modular housing for your controller (if using CompactRIO) and C Series modules. A high-performance backplane in the chassis contains the system's data, timing, and triggering buses.
The controller runs your application and interfaces with your C Series modules. If you are using the NI CompactDAQ platform, then a Personal Computer (PC) will act as the controller of your system. However, if the CompactRIO platform is used then an embedded real-time controller will be used instead.
You need software to interface with your hardware and to collect, analyze, present, and store your measurements. This device is compatible with a different programming languages depending on the platform used. If you are using the NI CompactDAQ platform then this device is compatible with LabVIEW, C/C++, Visual Basic, and .NET. However, if the CompactRIO platform is used then this device requires the LabVIEW FPGA Module (sold separately), the LabVIEW Real-Time Module (sold separately) and NI-RIO driver software (included with the hardware).
