National Instruments 779026-01 Multifunction I/O Module 

National Instruments part number 779026-01 is an identifying part number for the USB-6009, a USB Multifunction I/O Device. This device offers analog I/O, digital I/O, and a 32‑bit counter. It has 8 Analog Inputs (14-bit, 48 kS/s), 2 Analog Outputs (150 Hz), and 12 Digital Inputs/Outputs. It provides essential functionality for applications like simple data logging, portable measurements, and academic lab experiments. The device features a lightweight enclosure and is bus-powered for easy portability. Connecting sensors and signals to the USB‑6009 is straightforward with its screw-terminal connectivity. 

The included NI‑DAQmx driver and configuration utility streamline configuration and measurements. This device features 12 digital lines across two ports. Port 0 includes eight lines, while Port 1 has four lines. GND serves as the ground-reference signal for the digital I/O ports. Each line can be individually programmed as either an input or an output. The NI 779026-01 comes with eight analog input channels, suitable for either four differential analog input measurements or eight single-ended analog input measurements. 

The analog output of this device has two channels with a resolution of 12 bits. These outputs have a maximum update rate of 150 Hz, which is software-timed. The output range spans from 0 V to +5 V, and the output impedance is 50 Ω. 

Additionally, the output current drive capability is 5 mA. The 779026-01 features a single counter with a resolution of 32 bits. This counter is capable of edge counting, specifically detecting falling-edge events. Additionally, it operates in a count-up direction.
