National Instruments USB-6225 Multifunction I/O Device

The USB-6225 (Part Numbers: 779974-01, 779973-02, 779973-04, 779973-01, 779974-04) is a Multifunction I/O Device created by National Instruments. This device provides superior accuracy along with fast sampling rates. This device has 80 analog input channels. These channels can be used as 80 single-ended channels. The user can also utilize these channels as 40 differential channels. The NI USB-6225 offers 16-bit ADC resolution and the maximum sample rate of 250 kS/s for a single channel. For multiple channels, the maximum sample rate is also 250 kS/s. The timing accuracy of the input channels is 50 ppm of the sample rate. The device has a recommended warm-up time of 30 minutes, and should be calibrated at least once a year.

The USB 6225 NI has different input ranges. The input ranges include ±0.2V, ±1V, ±5V, and ±10V. The value of maximum working voltage for analog inputs of this device is ±11V. The input FIFO size for this device is 4,095 samples. The NI USB-6225 DAQ provides an overvoltage protection for all analog input channels and all sense channels. The input current of this instrument during the overvoltage condition is ±20 mA maximum.

The NI USB-6225 M Series DAQ has two analog output channels. Both channels provide 16 bit DAC resolution. The analog output channels have 16-bit monotonicity. The maximum update rate for one output channel is 833 kS/s. For both channels, the maximum update rate is 740 kS/s. The timing accuracy of the output channels is 50 ppm of the sample rate. The output range of this device is ±10 V. The output impedance is 0.2 Ω. The output channels provide an overdrive protection up to ±25 Volts.

The screw terminal fitted model of the device weighs 2 lb, and measures 10.5 x 6.73 x 1.75 in. in physical dimensions. Also, the Mass termination model weighs 2 lb, and has the physical dimensions: 7.4 x 6.73 x 1.75 in. The NI device has recommended operating and storage temperature ranges of 0 ºC to 45 ºC and -20 ºC to 70 ºC respectively, and a noncondensing humidity range of 10% RH to 90% RH.
