National Instruments PCI-6225 Multifunction DAQ

The National Instruments PCI-6225 (Part number: 779295-01) is a 16-Bit Multifunction DAQ. This low cost board offers 80 Analog Inputs, 2 Analog Outputs, 16 Digital Inputs, 32 Digital Outputs, and 2 Counters/Timers (32-bit). The NI PCI-6225 delivers reliable data acquisition capabilities for a broad range of applications since users can also add high-voltage measurement capability and sensors to this device by using SCC modules. Featured with 40 differential or 80 single ended DC coupled analog input channels, 16-bit ADC resolution, and 250 kS/s sampling rate, the NI PCI-6225 becomes an ultimate choice for applications where high channel count is required. The device is equipped with 2 68-pin VHDCI I/O connectors.
Unlike various other low-cost DAQ devices, this model has redundant analog outputs with a 16-bit resolution digital-to-analog converter. On its analog outputs, the user will be able to achieve 833 kS/s maximum update rate while operating with 1 channel and 740 kS/s (per channel) guaranteed update rate when using both channels. The NI PCI 6225 takes only 15 minutes for a complete warm-up and its calibration interval as defined by the vendor is 1 year.

The PCI 6225 is run using the NIDAQmx driver software which is compatible with software packages/application development environments such as LabVIEW or LabWindows/CVI.

The PFI/ Port 1 and Port 2 incorporated in this model can be used as static digital inputs. The digital inputs provided in this module are bidirectional; each one of them can be programmed as an input or output through software. This Multifunction DAQ comes equipped with 2,047 samples FIFO for waveform generation through its DO and another 2,047 samples FIFO is provided for waveform acquisition through DI. Moreover, the NI PCI-6225 offers 0 to 1 MHz DI or DO Sample Clock frequency.

The PCI-6225 weighs 0.23 lb, and measures 3.8 x 6.1 in. in physical dimensions. It has recommended operating and storage temperature ranges of 0 ºC to 55 ºC and -20 ºC to 70 ºC respectively, non-condensing relative humidity range of 10 to 90%, operating and non-operating random vibrations of 0.3 grms and 2.4 grms respectively – all at a frequency range of 5 to 500 Hz.

The PCI-6225 is available to be calibrated. While the recommended calibration period for individual parts varies, most parts should be calibrated either annually or every two years to ensure accuracy. If you need the PCI-6225 calibrated, Apex Waves provides options. We offer high-quality NIST accredited calibrations through a 3rd party, with an average turnaround time of 1 to 2 weeks. When you order the PCI-6225 with us, you can request basic (unaccredited) in-house calibration that will calibrate the part to the manufacturer specifications prior to being shipped.
