Description
The National Instruments USB-6225 is a versatile Multifunction I/O Device that offers a wide array of features suitable for various data acquisition needs. It includes 80 single-ended or 40 differential analog input channels with a high 16-bit ADC resolution, ensuring precise measurements. The device can handle a maximum sample rate of 250 kS/s for both single and multiple channels, with a timing accuracy of 50 ppm of the sample rate.
For optimal performance, a recommended warm-up time of 30 minutes is advised, and to maintain accuracy, calibration is required at least once a year. The USB-6225 can accommodate various input ranges of ±0.2V, ±1V, ±5V, and ±10V, and it is designed to handle a maximum working voltage of ±11V for analog inputs. With an input FIFO size of 4,095 samples and the capacity to withstand an input current of ±20 mA maximum during overvoltage conditions, this device is both robust and reliable for rigorous applications.
