The National Instruments USB-6225 is a PC-based multifunction data acquisition (DAQ) device. This model is designed to cater to a wide array of applications, thanks to its versatile specifications. Manufactured by National Instruments, a leader in the field, the USB-6225 stands out with its robust feature set.
Among its notable specifications are the part numbers 779974-01, 779973-02, 779973-04, 779973-01, and 779974-04, making it easy to identify and order. The device is equipped with 80 analog input channels, which can be configured as 40 differential or 80 single-ended channels, providing flexibility in connection and measurement types.
With a 16-bit Analog-to-Digital Converter (ADC) resolution, the USB-6225 ensures precise data measurement. The device offers a maximum sample rate of 250 kS/s for both single and multiple channel configurations, ensuring high-speed data collection without sacrificing accuracy.
The timing accuracy of the USB-6225 is 50 ppm of the sample rate, which guarantees precise timing for the measurement tasks. Furthermore, it is recommended that the device is warmed up for 30 minutes before use to ensure optimal performance. To maintain accuracy and reliability, calibration is recommended at least once a year.
The USB-6225 supports multiple input ranges, including ±0.2V, ±1V, ±5V, and ±10V, offering versatility for different measurement needs. It also has a maximum working voltage on analog inputs of ±11V, providing a safe margin above the input ranges. The device is equipped with an input FIFO size of 4,095 samples, allowing for efficient data buffering.
For protection against unexpected conditions, the USB-6225 includes overvoltage protection for all analog input and sense channels. In an overvoltage condition, the input current is limited to ±20 mA maximum, safeguarding the device and connected equipment.
In terms of output capabilities, the USB-6225 is not lacking
