The National Instruments PCI-6052E is a multifunction data acquisition board for PCI systems, delivering 16-bit analog I/O, digital I/O, and advanced timing control. It supports 16 single-ended or 8 differential analog input channels at up to 333 kS/s, two 16-bit analog outputs, eight programmable digital I/O lines, and two 24-bit counter/timers. The board integrates analog and digital triggering, a 512-sample FIFO buffer with three DMA channels, and compatibility with SCC and SCXI signal conditioning modules—making it suitable for automated testing, data logging, and process control across laboratory, research, and manufacturing environments.
