Each analog input features its own Sigma-Delta A/D converter, supporting sampling rates up to 41.6 kHz per channel. A wide range of digital I/O functions allow flexible use in a wide range of applications. In addition to the 16 analog inputs, the USB data acquisition module provides eight digital inputs, eight digital outputs, and two counter/timers.
An additional tachometer input can measure rotational speeds and also be used for phase measurements between the tachometer input and the A/D samples, achieving a resolution of 82 ns (0.005 degrees) at up to 10,000 rpm.
The 16 analog, 8 digital and 2 counter input channels are galvanically isolated to protect the computer; they can be run simultaneously and synchronously at 41.6 kHz. The comprehensive set of features also includes integrated anti-aliasing filters and software programmable trigger functions.
The module comes in two versions – as a rugged metal BNC connection box and as an OEM embedded board-level version for easy integration into custom applications. Despite its extensive functionality, the DT9826 runs entirely on USB power so that no external power supply is needed.
