The PCI-6221 is a PC-based Multifunction Data Acquisition (DAQ) device that belongs to the M Series. This device has part numbers 779066-01 and 779418-01, accommodating a variety of setups for different applications.
It features 16 single-ended or 8 differential analog input channels with a resolution of 16 bits, ensuring precise data capture. The analog inputs have an absolute accuracy of 3100 uV, providing reliable measurements. However, it does not support simultaneous sampling, which might be a consideration for some applications.
The data acquisition rate of this device reaches up to 250 kS/s, suitable for a wide range of data collection needs. For output, it offers 2 analog output channels with an impressive rate of 833 kS/s for a single channel and 740 kS/s for dual channels, enabling quick responses in control applications.
Powering the PCI-6221 is convenient, as it is bus-powered and compatible with both 3.3 V and 5 V signal environments. This flexibility ensures it can be easily integrated into various systems without requiring additional power supplies.
In addition to analog capabilities, this device includes two 32-bit counters/timers, enhancing its functionality for applications requiring precise timing and counting. For digital I/O, it offers 8 correlated digital I/O channels on a 68-pin connector and 2 correlated channels on a 37-pin connector, with a digital I/O rate of up to 1 MHz. This allows for high-speed digital communication and control.
The PCI-6221 is a versatile and reliable choice for users needing a multifunctional DAQ device for their PC-based applications.
