National Instruments 779116-01 Multifunction I/O Module 

National Instruments part number 779116-01 is an identifying part number for the PXI-6250, a Multifunction I/O Module. The 779116-01 has a sampling rate of 1.25 MS/s and a resolution of 16 bits. It offers two 32-bit counters/timers, correlated digital I/O, analog and digital triggering, and analog input. 

This device provides reliable and affordable DAQ capabilities that may be used for a variety of tasks, such as research, design verification/test, industrial testing, and lab automation. SCC or SCXI signal conditioning modules allow users to add sensor and high-voltage measurement capabilities to their devices. This Module is compatible with NI-DAQmx driver software, LabVIEW SignalExpress LE data-logging software, and the Measurement & Automation Explorer configuration utility. The digital lines on the 779116-01 module can drive 24 mA for actuator and relay control. Pumps, valves, lights, fans, and motors may all be controlled using pulse-width modulation when the digital lines on the module are clocked at 10 MHz by the user.

Additionally, the NI 779116-01 can be used with NI Analog Output Devices for 64 or more loops. When comparing channels with similar input ranges, the settling time increases as the step between channels increases. If users are aware of the typical input range of their signals, they can group signals with similar expected ranges together in their scan list. For voltage inputs exceeding 10 V or sensor measurements, users should employ signal conditioning accessories. Using DMA or interrupts, buffered acquisition data is moved from the onboard FIFO memory of the NI 779116-01 Multifunction I/O Module to a PC buffer and then to the application memory.
