Description
The PCI-6221 is a PC-based Multifunction DAQ device manufactured by National Instruments and belongs to the M Series. It is designed to cater to a wide range of data acquisition and signal processing needs. The device features part numbers 779066-01 and 779418-01, indicating different configurations or packaging options available.
It offers 16 single-ended or 8 differential analog input channels with a 16-bit analog input resolution. These features ensure precise measurement capabilities. The DAQ device has a data acquisition rate of 250 kS/s, allowing for efficient data collection. Additionally, it provides 2 analog output channels capable of delivering an output rate of 833 kS/s for a single channel and 740 kS/s for dual channels, enabling high-speed signal generation.
The PCI-6221 operates in a bus-powered configuration compatible with both 3.3 V and 5 V signal environments, ensuring versatility in power supply requirements. With an analog input absolute accuracy of 3100 uV, it guarantees precise measurements. Despite not supporting simultaneous sampling, the device can achieve a maximum sample rate of 250 kS/s.
It features two 32-bit counters/timers and supports digital triggering, enhancing its functionality in complex applications. The device is compatible with NI SCC and SCXI signal conditioning platforms, offering flexibility in signal conditioning options. The correlated digital I/O (DIO) capability includes 8 channels for the 68-pin version up to 1 MHz and 2 channels for the 37-pin version, catering to diverse digital interfacing needs.
Furthermore, the PCI-6221 is equipped with 6 DMA channels, facilitating efficient data transfer. It has a lightweight design, weighing only 3.2 oz., and its compact dimensions of 4.2 x 6.1 in make it suitable
