The National Instruments PCI-6031E is a multifunction data acquisition board for PCI bus systems, delivering analog input, analog output, and digital I/O capabilities for industrial and laboratory measurement, control, and logging applications. Built around the NI DAQ-STC timing controller and MITE bus interface, the 6031E provides onboard self-calibration, temperature drift protection, and hardware triggering to maintain measurement accuracy without manual calibration. Multi-device synchronization via RTSI or PXI trigger buses enables integrated measurement systems across up to five PCI E Series boards.
