Description
The PCI-6221 is a PC-based Multifunction Data Acquisition (DAQ) device that belongs to the M Series and is manufactured by National Instruments. This device comes with part numbers 779066-01 and 779418-01. It is designed to cater to a wide range of measurement and control applications.
The PCI-6221 features 16 single-ended or 8 differential analog input channels with a resolution of 16 bits, ensuring precise data collection. The data acquisition rate of this device reaches up to 250 kS per second, allowing for efficient data capture.
For output, the device offers 2 Analog Output (AO) channels with an AO rate of 833 kS per second for a single channel and 740 kS per second for dual channels, facilitating rapid response to control signals. The PCI-6221 operates in a bus-powered mode, compatible with both 3.3 V and 5 V signal environments, providing flexibility in power requirements.
The analog input absolute accuracy of the device is 3100 uV, which highlights its capability to perform precise measurements. Despite its high sample rate of 250 kS per second, the PCI-6221 does not support simultaneous sampling, which may need consideration based on the application requirements.
Additionally, the device is equipped with two 32-bit counters/timers and 8 correlated digital I/O, expanding its utility in various data acquisition and control tasks. The PCI-6221 is a versatile and efficient choice for users seeking a reliable DAQ solution from National Instruments.
