    The ADQ-412 in the ALLDAQ shop

    Precise & dynamic current measurement up to 50 A


    The ADQ-412 CompactPCI board serves for PC based current measurement up to 50 A. 2 isolated analog input channels with the current measurement ranges ±25 mA and ±50 A are provided. The relay controlled change-over between the both shunts (10 Ω / 5 mΩ) is typically handled by your application without interrupting the circuit.

    A hardware comparator automatically switches into the 50 A range as soon as the 25 mA range is exceeded by more than 12.5%. This protection mechanism works independently from operating system and application software. An appropriate interrupt event will be generated and can be evaluated by the application.

    User-specific adjustment

    The ALLDAQ ADQ-412 offers a smart possibility to perform an user-specific adjustment. Depending on the application the user has the possibility to store specific adjustment data into an EEPROM additionally to the factory adjustment data (which can´t be overwritten).

    By the ALLDAQ-Manager the user can select whether the factory or user adjustment should be activated when booting the computer.

    Software Support

    • Drivers for Windows 10/8.1/8/7/Vista SP2 (32/64 bit)
    • API with a unique programming logic for Windows
    • Programming support (SDK) with examples for C++, C#, Visual Basic, Delphi/Pascal and Python included
    • ALLDAQ-Manager - Utility software offers a central access to the parameters of the ALLDAQ driver system and the help files
    • Virtual Instruments (VIs) for LabVIEW™
    • MATLAB® interface with examples and help file
