Description
The PCI-6221 is a PC-based Multifunction Data Acquisition (DAQ) device that is part of the M Series. It comes with part numbers 779066-01 and 779418-01, indicating different configurations or package contents. This DAQ device is well-suited for a variety of applications requiring high-speed data acquisition and processing due to its robust feature set.
One of the key features of the PCI-6221 is its analog input channels. It offers 16 single-ended or 8 differential channels, providing flexibility in connecting a variety of sensors. The analog input resolution is 16 bits, ensuring precise data capture. The device is capable of a data acquisition rate of up to 250 kS/s, making it suitable for capturing fast-changing signals.
In terms of output capabilities, the PCI-6221 provides 2 analog output channels with a maximum output rate of 833 kS/s for a single channel and 740 kS/s when both channels are used simultaneously. This high-speed analog output capability allows for the generation of precise control signals and waveforms.
The device operates with a bus power requirement of either 3.3 V or 5 V, offering compatibility with a wide range of PC motherboards. The analog input absolute accuracy is rated at 3100 uV, ensuring accurate data collection for precise measurements.
Despite its high-speed data acquisition capabilities, the PCI-6221 is not equipped with simultaneous sampling, which could be a consideration for applications requiring synchronized multi-channel data acquisition. However, it compensates with 2 32-bit counters/timers, providing ample functionality for timing and counting tasks.
Digital triggering is supported, enabling users to start data acquisition based on specific events or conditions. Additionally, the device features correlated digital I/O (DIO) with 8 channels available in the 68-pin version, further expanding its utility for complex data acquisition and
