Description
The PCI-6221 is a PC-based Multifunction DAQ device, part of the M Series, and manufactured by National Instruments. It offers a range of features designed for a variety of data acquisition applications. This device comes with part numbers 779066-01 and 779418-01, making it easily identifiable for procurement and support.
With 16 single-ended or 8 differential analog input channels, it provides flexibility in connecting a variety of sensors. The analog inputs have a resolution of 16 bits, ensuring precise measurement outcomes. The PCI-6221 supports a data acquisition rate of up to 250 kS per second, which is optimal for capturing fast transient signals as well as for general-purpose monitoring.
Furthermore, the device includes 2 analog output (AO) channels, capable of reaching an AO rate of 833 kS per second when operating in single channel mode and 740 kS per second with dual channels. This feature allows for the generation of precise control signals or the output of synthesized waveforms.
The PCI-6221 is designed to be bus powered, with support for both 3.3 V or 5 V signal environments. This makes it highly versatile and easily integrated into a range of signal acquisition environments without the need for external power sources. Its analog input absolute accuracy is rated at 3100 uV, ensuring reliable measurement accuracy for critical applications.
Despite its high sample rate capability, it does not support simultaneous sampling, which may be a consideration for applications requiring synchronized sampling across multiple channels. However, it compensates with 2 32-bit counters/timers, enhancing its utility in complex measurement and control tasks.
The device also features digital I/O (DIO), further expanding its versatility in interfacing with external devices for control and signaling purposes. The PCI-6221 stands as a comprehensive solution for a wide range of data acquisition needs, embodying the quality and reliability associated with National Instruments’ products.
