The National Instruments part number 778629-01 is a multifunction data acquisition (DAQ) device designed for diverse applications across industrial automation, laboratory automation, research, and production testing. Based on the PCI-6013 model, this device integrates analog input, digital input/output, counters, and digital triggering within a single unit, providing the versatility required for both OEM products and simpler applications. The DAQ supports two selectable input modes: differential (DIFF) mode, which allows for up to eight channels, and nonreferenced single-ended (NRSE) mode, which accommodates up to 16 channels. To optimize the resolution of its 24-bit analog-to-digital converter (ADC), each channel can be independently set with programmable gains of 0.5, 1.0, 10, or 100, adapting to specific application requirements. In addition to its analog capabilities, the device features eight digital I/O lines (DIO<0..7>), which can be configured as either input or output, enhancing its suitability for various automation and control tasks. With two 24-bit counters and integrated digital triggering, the 778629-01 excels in precise timing management and synchronization, facilitating smooth sampling rate transitions, pulse generation, and equivalent time sampling. The built-in DAQ-STC (data acquisition system timing controller) chip ensures effective handling of time-sensitive operations, delivering a maximum timing resolution of 50 ns across three distinct timing groups. Programmable Function Input (PFI) pins expand the device's connectivity options, enabling seamless interaction with external electronics and enhancing integration potential in complex automation environments.
