Description
The PCI-6221 is a PC-based Multifunction DAQ device that comes with part numbers 779066-01 and 779418-01. This device is specifically designed for a wide range of applications with its 37-Pin D-Sub connector, featuring 16 Analog Inputs (AI), 10 Digital I/O (DIO), and 2 Analog Outputs (AO). The analog inputs can be configured as either 16 single-ended channels or 8 differential channels, providing flexibility in measurement types.
The analog input resolution is 16 bits, ensuring high accuracy in readings. The PCI-6221 is capable of a data acquisition rate of 250 kS/s, which allows for rapid data collection. Furthermore, the analog output rate can reach up to 833 kS/s for a single channel and 740 kS/s for dual channels, enabling efficient data output.
In terms of accuracy, the analog input absolute accuracy is 3100 µV, which is crucial for precise measurements. However, it’s important to note that this device does not support simultaneous sampling, which may be a consideration for certain applications. The digital I/O includes 8 correlated (1 MHz for 68-pin) and 2 correlated (37-pin), along with two 32-bit counters/timers, enhancing its functionality for a variety of tasks.
Compatibility with signal conditioning platforms NI SCC and SCXI is also a feature of the PCI-6221, making it versatile for different signal types and applications. Lastly, the device is bus powered with a 3.3 V requirement, simplifying the power setup and reducing the need for external power sources. Overall, the PCI-6221 is a robust and multifunctional DAQ device, suitable for a broad range of data acquisition and control applications.
