National Instruments 779070-01 Multifunction I/O Device

National Instruments developed the 779070-01 as a component of the PCI-6251 Model series for multifunction data acquisition (DAQ) applications. It is a dependable option for a variety of applications, including research, design verification/testing, laboratory automation, and production test procedures. Its capacity to give precise measurements at fast speeds sets it apart.

This multipurpose I/O device has an extensive range of capabilities designed to satisfy the most exacting DAQ specifications. Superior accuracy is ensured even at high sampling rates because of its 16 analog inputs, each of which operates at a maximum sampling rate of 1.25 MS/s and 16-bit resolution. It also has two analog outputs with a maximum sampling rate of 2.8 MS/s and a resolution of 16 bits. In order to increase its adaptability in a range of measurement and control applications, the device additionally has two 32-bit counters/timers, 24 digital I/O lines, and analog and digital triggering capabilities.

The 779070-01 is distinguished by its two-year calibration period for increased reliability and its NI-MCal calibration technology, which improves measurement precision. Additionally, it has an integrated NI-PGIA 2 amplifier, which guarantees quick settling times at high scanning speeds and retains 16-bit accuracy on all channels—even when operating at full load.

The device's capability is further expanded by its interoperability with the NI SCC and SCXI signal conditioning platforms, which makes it simple for users to add sensor and high-voltage measurement capabilities. Additionally, these systems allow for the digital storage of sensor data sheet information for simplified sensor integration through compatibility with IEEE 1451.4 smart transducer electronic data sheet (TEDS) sensors.

The 779070-01's ability to drive digital lines at up to 10 MHz makes it an excellent choice for control applications in addition to standard DAQ chores. With the help of this capability, you may precisely control a variety of actuators and devices, including pumps, motors, and valves, by using pulse-width modulation (PWM). The device can be used for a variety of control applications because it supports protected digital lines, digital debounce filters, and quadrature encoder measurements.

Moreover, rapid and effective design verification tests are made possible by the device's smooth interaction with NI LabVIEW SignalExpress software, which also makes it possible to convert projects into LabVIEW programs for immediate DAQ use and analyze designs on the fly.
