Description
The National Instruments USB-6225 is a multifunction I/O device designed for a wide range of applications. With its robust set of specifications, it stands out as a versatile tool for professionals seeking reliable data acquisition and control.
This device is capable of handling 80 single-ended or 40 differential analog input channels, providing flexibility for various measurement setups. It boasts a 16-bit ADC resolution, ensuring precise and accurate data capture. The USB-6225 can achieve a maximum sample rate of 250 kS/s (samples per second), whether utilizing single or multiple channels, making it suitable for high-speed data acquisition tasks.
Accuracy is key in data acquisition, and the USB-6225 delivers with a timing accuracy of 50 ppm (parts per million) of the sample rate. To achieve optimal performance, it is recommended that the device warms up for 30 minutes before use. Additionally, to maintain its precision, a calibration period of at least once a year is advised.
The device supports multiple input ranges, including ±0.2V, ±1V, ±5V, and ±10V, providing versatility for various signal measurements. It is designed to handle a maximum working voltage (for analog inputs) of ±11V, and it is equipped with a sizable input FIFO (First In, First Out) size of 4,095 samples, enhancing its data handling capabilities.
One of the key features of the USB-6225 is its overvoltage protection on all analog input and sense channels, safeguarding the device against unexpected voltage spikes. In the event of an overvoltage condition, the input current is limited to ±20 mA, further protecting the device from damage.
The USB-6225 is identified by several part numbers, including 779974-01, 779973-02, 779973-04, 779973-01, and 779974-04, making it easy to identify and procure for your specific application needs.
