Isolated 32 AI (16-Bit, 250 kS/s), 2 AO (250 kS/s), 8 DI, 8 DIO USB Multifunction I/O Device

Overview

The USB-6218 is an isolated, multifunction DAQ device. It offers analog I/O, digital input, digital output, and two 32-bit counters. For improved accuracy and safety, the USB-6218 provides 60 V, CAT I isolation. It also features signal streaming technology that gives you DMA-like bidirectional high-speed streaming of data across USB. The device is ideal for test, control, and design applications including portable data logging, field monitoring, embedded OEM, in-vehicle data acquisition, and academic. The included NI-DAQmx driver and configuration utility simplify configuration and measurements.

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.
