Description
The PCI-6221 is a PC-based Multifunction Data Acquisition (DAQ) device that falls under the M Series category, manufactured by National Instruments. This model has a part number of 779418-51, with alternative part numbers including 779066-01 and 779418-01. It is designed to provide a high level of performance and flexibility for various data acquisition tasks.
The device features 16 single-ended or 8 differential analog input channels, along with 2 analog output channels. The analog inputs have a resolution of 16 bits, ensuring precise data capture. The data acquisition rate of the PCI-6221 is up to 250 kS/s, while the analog output can achieve rates of 833 kS/s for a single channel and 740 kS/s for dual channels. The analog input absolute accuracy is specified at 3100 uV, indicating the device’s high accuracy in measurements.
In addition to its analog capabilities, the PCI-6221 includes 8 correlated (clocked) digital I/O for the 68-pin version at speeds up to 1 MHz, and 2 correlated (clocked) digital I/O for the 37-pin version. It also features 2 x 32-bit counters/timers, providing additional functionality for timing and counting operations.
Furthermore, this DAQ device is compatible with NI SCC (Signal Conditioning Compatibility), allowing for enhanced signal processing capabilities. This compatibility ensures that the PCI-6221 can be used in a wide range of applications, from simple data logging to more complex signal analysis and control tasks.
