Description
The PCIe-6321 is a PC-based Multifunction DAQ part of the X Series DAQ, identified by part numbers 194986D-04L / 781044-01. This device is designed to cater to a wide range of data acquisition and signal processing needs. It features 16 AI (Analog Inputs) which can be configured as 16 single-ended channels or 8 differential channels, providing flexibility for various measurement requirements.
In addition to its analog inputs, the PCIe-6321 offers 2 AO (Analog Outputs) and 24 DIO (Digital Input/Output) channels. These features enable the device to handle a variety of tasks, from simple data logging to more complex control and automation applications. The device also boasts four 32-bit timers, enhancing its capability to manage time-sensitive operations efficiently.
With a maximum sample rate of 250 kS/s, the PCIe-6321 ensures high-speed data acquisition, making it suitable for capturing fast transient signals as well as for long-term monitoring tasks. It supports an external base clock frequency range from 0 to 25 MHz, with a base clock accuracy of 50 ppm, ensuring precise timing and synchronization of data acquisition processes.
The operational temperature range of 0 °C to 50 °C allows the PCIe-6321 to perform reliably in a variety of environments. Furthermore, the device is equipped with 8 DMA (Direct Memory Access) channels, facilitating fast and efficient data transfer between the DAQ device and the host PC without burdening the CPU.
External digital triggers are supported through any PFI (Programmable Function Interface) and RTSI (Real-Time System Integration) source, offering versatility in triggering and synchronization options for complex experiments or industrial processes. Lastly, the device comes with a calibration feature, which is available and recommended annually or every two years to ensure accuracy and reliability in measurements.
