20-bit, 1MS/s/ch (16 AI, 2 AO, 16 DIO) mioDAQ, USB Multifunction I/O Device

Overview

The USB-6451 is a USB Type-C bus-powered mioDAQ device with analog I/O, digital I/O, and four counters. It features 8 simultaneous sampling analog-to-digital converters (ADCs) with four input range settings from ± 200 mV to ± 10 V, to help you optimize the resolution of your measurements. The analog output channels can output ± 10 V with update rates of 250 kS/s/ch. Additionally, the USB-6451 digital I/O channels can function as static input or output channels, hardware-timed channels up to 10 MHz, or as triggers, clocks, or I/O for the four onboard counters. The USB-6451 also supports FlexLogger Lite, free data acquisition software from NI, and includes documented APIs and examples for LabVIEW, Python, C/C++, and more. You can choose an OEM version of the USB-6451, which ships as a non-enclosed, board-only device with 50-pin board-level connectors instead of spring terminals.

USB-6451 Accessories and Software

Software (2)

Product (Part Number) Description	Recommended use cases
FlexLogger Professional (785748-3501) FlexLogger Professional, Subscription License, Download	Recommended for automated, extensible data logging with NI data acquisition (DAQ) hardware. Automate tests using alarms, triggers, and events, and expand capabilities with plug-ins. Key Features Multichassis synchronization—Synchronize multiple NI chassis for accurate, time-aligned measurements across high channel counts. Logging triggers—Start, stop, or segment data recording automatically based on sensor thresholds or other conditions to capture only what matters. Events—Respond to specific occurrences during a test, such as activating equipment when a condition is met (for example, start cooling fans when temperature exceeds a limit). Automation APIs—Control and monitor FlexLogger from external applications (Python, NI LabVIEW, or NI TestStand), enabling integration into larger automated test systems. Calculation channels—Perform real-time math on acquired data (averages, RMS, custom formulas) to track derived measurements as the test runs. Plug-ins—Extend FlexLogger with custom LabVIEW or Python plug-ins to integrate third-party hardware, perform custom analysis, or connect to lab systems. CAN/LIN logging—Acquire and log automotive network data alongside sensor measurements for complete vehicle or subsystem testing.	View Product Details
LabVIEW+ Suite (788509-35) NI LabVIEW+ Suite, Subscription License, Download	Recommended for engineers building full test and validation systems where modular code development and higher-level frameworks are needed to accelerate development for shorter time to market. The LabVIEW+ Suite includes the following products: NI LabVIEW—Provides a graphical programming environment for test system development, enabling connectivity to any instrument and fully integrated user interfaces. NI TestStand—Eliminates the need for time-intensive in-house sequencer development and maintenance by providing an off-the-shelf test management software for validation and production test. NI DIAdem—Saves engineers hundreds of hours of manual data analysis and report creation with automation. NI FlexLogger™ software—Simplifies data acquisition and data logging with interactive measurement setup for NI DAQ hardware. NI InstrumentStudio™ software—Provides a central location for configuration, measurement, and automation.	View Product Details
