NI PCIE-6343 is an NI X Series PCI Express multifunction I/O device intended for mixed-signal measurement and control tasks. NI identifies the model as a PCI Express board with 32 analog inputs, 4 analog outputs, 48 digital I/O channels, and four 32-bit counters/timers. The official NI model page also lists the exact part number 781047-01 for the PCIe-6343, while the broader X Series family designation describes the device class rather than a separate SKU variant. https://www.ni.com/en/shop/hardware/voltage/model-pcie-6343?partNumber=781047-01
For analog acquisition, the PCIe-6343 provides 32 single-ended or 16 differential analog input channels with 16-bit resolution. NI specifies a maximum analog input sample rate of 500 kS/s for single-channel operation and 500 kS/s aggregate for multichannel acquisition. Supported input ranges are ±0.2 V, ±1 V, ±5 V, and ±10 V, and the maximum working voltage for analog inputs is ±11 V of AI GND. NI also specifies an input FIFO of 4,095 samples and scan list memory of 4,095 entries, with DMA (scatter-gather) and programmed I/O data transfer modes. https://www.ni.com/docs/en-US/bundle/pcie-6343-specs/page/specs.html
On the output and digital side, NI specifies four 16-bit analog output channels with a 900 kS/s update rate and a voltage range of -10 V to 10 V. The board also includes 48 bidirectional digital channels and four 32-bit counters/timers. NI further states that X Series devices such as the PCIe-6343 use NI-STC3 timing and synchronization technology, including independent analog and digital timing engines and retriggerable tasks. https://www.ni.com/en/shop/hardware/voltage/model-pcie-6343?partNumber=781047-01
