National Instruments 779070-01

The National Instruments 779070-01 is a multifunction I/O device from the PCI-6251 series, engineered to address diverse data acquisition (DAQ) needs across applications such as research, design verification, laboratory automation, and production testing. This robust device delivers high precision in measurements, characterized by 16 analog inputs capable of achieving a sampling rate of 1.25 MS/s at a 16-bit resolution, ensuring exceptional accuracy even at high speeds. Additionally, it features two analog outputs that support a maximum sampling rate of 2.8 MS/s, also maintaining a 16-bit resolution. The 779070-01 includes two 32-bit counters/timers and 24 digital I/O lines, supplemented by analog and digital triggering capabilities, thus enhancing its versatility for various measurement and control applications.

The device incorporates NI-MCal calibration technology that provides superior measurement accuracy, complemented by a two-year calibration period to ensure reliability. An integrated NI-PGIA 2 amplifier supports quick settling times even at high scanning speeds, retaining 16-bit accuracy across all channels, regardless of load conditions. Compatibility with the NI SCC and SCXI signal conditioning platforms enhances the device's functionality, allowing for the easy integration of sensor and high-voltage measurement capabilities, as well as digital storage of sensor data sheet information using IEEE 1451.4 smart transducer electronic data sheet (TEDS) sensors.

In addition to standard DAQ functions, the 779070-01 excels in control applications, driving digital lines at speeds up to 10 MHz, which enables precise control of various actuators and devices through pulse-width modulation (PWM). This device supports protected digital lines, digital debounce filters, and quadrature encoder measurements, making it suitable for a wide range of control tasks. Its seamless integration with NI LabVIEW SignalExpress software facilitates rapid design verification testing and allows users to easily convert projects into LabVIEW programs for immediate DAQ use and real-time design analysis.
