Description
The USB-6225 is a multifunction I/O device developed by National Instruments, known for its robust capabilities in handling a wide range of data acquisition tasks. This device is well-suited for various applications due to its comprehensive specifications.
It supports a vast array of analog input channels, offering flexibility with 80 single-ended channels or 40 differential channels. This versatility ensures that it can be adapted to many different types of sensors and inputs. The 16-bit ADC resolution enhances the precision and quality of measurements, making it ideal for applications that require high accuracy.
The USB-6225 achieves a maximum sample rate of 250 kS/s, regardless of whether it is operating on a single channel or multiple channels. This capability ensures efficient data acquisition processes without compromising the speed. The timing accuracy is maintained at 50 ppm of the sample rate, guaranteeing precise timing for all measurements.
Before reaching optimal performance, the device requires a warm-up time of 30 minutes. To maintain its accuracy and reliability, it is recommended that the device undergoes calibration at least once a year.
The USB-6225 is designed to accommodate a variety of input ranges, including ±0.2V, ±1V, ±5V, and ±10V, with a maximum working voltage of ±11V. This feature allows users to connect a broad spectrum of signals without the need for external signal conditioning. The device is equipped with an input FIFO size of 4,095 samples, enhancing its data handling capabilities.
Furthermore, the USB-6225 provides overvoltage protection for all analog input channels, ensuring the longevity and safety of the device in environments where voltage spikes may occur. This protection is critical for preserving the integrity of both the device and the data collected.
It comes with various part numbers including 779974-01, 779973-02, 779973-04, 779973-01, and 779974-04, allowing for flexibility in ordering and replacement processes. This range of part numbers ensures that users can
