Description
The NI PCI-6221 is a PC-based multifunction DAQ device designed for a variety of applications. This device features Part Numbers 779066-01 and 779418-01, indicating its availability in different configurations to suit specific project requirements.
The PCI-6221 model falls under the category of PC-based Multifunction DAQ, offering a versatile solution for data acquisition needs. It is specifically described as the NI PCI-6221 with a 37-Pin D-Sub connector, including 16 Analog Inputs (AI), which can be configured as either 16 single-ended or 8 differential channels, 10 Digital I/O (DIO) channels, and 2 Analog Output (AO) channels. The analog outputs can reach a rate of 833 kS/s when used in a single channel configuration, and 740 kS/s when both channels are utilized simultaneously.
The device boasts a 16-bit Analog Input Resolution, ensuring precise measurements. The overall data acquisition rate is impressive at 250 kS/s, providing swift data collection capabilities. Furthermore, the PCI-6221 includes 2 32-bit Counters/Timers, enhancing its functionality for complex timing and counting tasks.
Additionally, the device offers correlated digital I/O capabilities, with a 1 MHz rate for the 68-pin configuration and 2 correlated channels for the 37-pin setup. Despite its extensive features, it does not support Simultaneous Sampling, which may be a consideration for certain applications requiring this functionality.
The Analog Input Absolute Accuracy of the device is specified at 3100 uV, indicating its precision in measuring and recording analog signals. Compatibility with NI SCC and SCXI signal conditioning platforms is also highlighted, allowing for flexible and scalable setups to match various experimental and industrial needs.
In summary, the NI PCI-6221 is a robust and versatile PC-based multifunction DAQ device, ideal for a wide range of data acquisition tasks. Its comprehensive set of features and compatibility options make it a valuable tool for engineers
