Description
The PCI-6221 is a PC-based Multifunction DAQ device, categorized under National Instruments’ M Series. This device comes with part numbers 779066-01 and 779418-01, indicating different variations or packaging options that are available.
It is designed to provide a robust and efficient solution for data acquisition, featuring 16 single-ended or 8 differential analog input channels. These channels are capable of a 16 bits resolution, ensuring precise data capture. The analog input absolute accuracy of the device is 3100 uV, which helps in maintaining the integrity of the data collected.
The PCI-6221 excels in data processing with a data acquisition rate of 250 kS/s, which is also its maximum sample rate. However, it does not support simultaneous sampling, directing its use towards applications where this feature is not a critical requirement.
For output functionalities, it is equipped with two analog output (AO) channels. These channels can operate at an AO rate of 833 kS/s for single-channel operations and 740 kS/s for dual channels, allowing for efficient data output.
In addition to its analog capabilities, the PCI-6221 includes two 32-bit counters/timers and offers flexible digital I/O options. It has 8 correlated (clocked) digital I/O for the 68-pin version up to 1 MHz, and 2 correlated (clocked) digital I/O for the 37-pin version, enhancing its utility in various application scenarios.
This multifunction DAQ device is tailored for users who need a versatile and reliable solution for their data acquisition needs, making it an excellent choice for a wide range of applications.
