Description
The PCI-6221 is a PC-based Multifunction Data Acquisition (DAQ) device, part of the esteemed M Series developed by National Instruments. This device is designed to cater to a wide range of applications requiring high-precision measurements and control. It features 16 single-ended or 8 differential analog input channels, offering flexibility in connecting various sensors and signals. With an analog input resolution of 16 bits, it ensures accurate data representation.
The PCI-6221 excels in data acquisition with a maximum sample rate of 250 kS per second, allowing for the capture of fast transient signals. Despite its high throughput, it does not support simultaneous sampling, which means each channel is sampled sequentially. For analog output, it is equipped with 2 channels, capable of an output rate of 833 kS per second for a single channel or 740 kS per second when both channels are used, enabling the generation of precise control signals or waveforms.
This device operates comfortably in both 3.3 V or 5 V signal environments, making it versatile for integration into various electrical setups. The analog input absolute accuracy is rated at 3100 uV, ensuring reliable measurements. Additionally, it includes two 32-bit counters/timers for tasks requiring precise timing and counting capabilities.
Digital triggering is another key feature of the PCI-6221, providing users with the ability to start acquisition or output sequences based on predefined signal events, enhancing the device’s application in complex measurement systems. With part numbers 779066-01 and 779418-01, this DAQ device stands out as a powerful tool for engineers and scientists in need of high-performance data acquisition and signal generation capabilities.
