NI USB-6218 (32 AI, 2 AO, 8 DI, 8 DIO)

Brand: National Instruments
Origin: Hungary, Malaysia, USA
Product code: USB-6218

    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 USB‑6218 features a lightweight mechanical enclosure and is bus powered for easy portability. The included NI‑DAQmx driver and configuration utility simplify configuration and measurements.

    • Isolated 32 AI (16-Bit, 250 kS/s)
    • 2 AO (250 kS/s)
    • 8 DI, 8 DIO USB
    •  Python, ANSI C, C#.NET, and MathWorks MATLAB® software.
