PCIe 6351 offers analog I/O, digital I/O, and four 32-bit counters/timers for PWM, encoder, frequency, event counting, and more. The device utilizes a high-throughput PCI Express bus and multi-core optimized drivers and application software to provide high performance capabilities. Onboard NI‑STC3 timing and synchronization technology provides advanced timing capabilities, including independent analog and digital timing engines and re-triggering measurement tasks. PCIe 6351 is suitable for a wide range of applications from basic data recording to control and test automation. The included NI‑DAQmx driver and configuration utility simplify configuration and measurement.

The PCI-6351 (Part number: 781048-01) is an X-series multi-function I/O device manufactured by National Instruments. The equipment complies with EMC standards, which are critical for electrical equipment used in laboratories. These standards are also essential for control and measurement purposes. NI is committed to planning and developing reliable products. The NI PCI-6351 is manufactured in the same way.

The NI PCI-6351 has a PCI Express interface and is compatible with 1 to 16 PCI Express slots. It enables the device to provide up to 16 digital input lines and 8 digital output lines over a DMA channel. NI devices have 16 differential or 8 single-ended analog input channels (with 16-bit resolution and a maximum sampling rate of 1.25 MS per second) and 2 analog output channels, also with 16-bit resolution. The maximum sampling rate is 2.86 MS per second. The NI PCI-6351 also has an external digital trigger that can be performed via any PFI or RSTI. These triggers have software-selectable polarity and are suitable for many signals. An external digital trigger has analog inputs and outputs. These inputs and outputs enable the device to boot and disconnect the trigger. It can also be used as a sampling clock time base and a sampling clock. The NI PCI-6351 can use other device bus interfaces to generate triggers. It uses RSTI as input and output media. The device also features a phase-locked loop and is equipped with a 68-pin VHDCI I/O connector.
