Description
The PCI-6221 is a PC-based Multifunction DAQ device that falls under the M Series category, manufactured by National Instruments. This device is designed to cater to a variety of data acquisition needs and comes with part numbers 779066-01 and 779418-01. It offers a versatile range of features tailored for precise and efficient data collection and analysis.
It is equipped with 16 single-ended or 8 differential analog input channels, providing the flexibility needed for various measurement requirements. These channels deliver data with a 16-bit resolution, ensuring high accuracy in the readings. The analog input absolute accuracy is rated at 3100 uV, which enhances the reliability of the measurements captured by the device.
The data acquisition rate of the PCI-6221 is an impressive 250 kS/s, allowing for rapid collection of data without compromising on quality. However, it does not support simultaneous sampling, which might be a consideration for real-time analysis needs. The device compensates for this with its high-speed analog output capabilities, featuring 2 channels that can operate at an output rate of 833 kS/s for a single channel and 740 kS/s for dual channels.
In addition to its analog capabilities, the PCI-6221 also provides robust digital functionality. It includes 8 correlated (clocked) Digital I/O for the 68-pin version up to 1 MHZ, and 2 correlated (clocked) DIO for the 37-pin version, offering versatility in handling digital signals alongside analog inputs and outputs.
Further enhancing its utility are the two 32-bit counters/timers, which allow for precise timing and counting operations, a critical feature for synchronized data acquisition and control tasks. The device is also bus-powered, compatible with both 3.3 V or 5 V signal environments, adding to its convenience and ease of integration into existing systems.
