Data Acquisition and Control Interface (DACI)

The Data Acquisition and Control Interface (DACI) is a versatile USB peripheral enclosed in a half-size EMS module. The DACI is intended to be used with the LVDAC-EMS software. Together, the DACI and LVDAC-EMS provide a complete set of modern computer-based instruments to measure, observe, analyze, and control electrical and mechanical parameters. The provided instruments include voltmeters, ammeters, power meters, frequency meters, efficiency meters, impedance meters, power factor meters, energy meters, torque and speed meters, an oscilloscope, a phasor analyzer, a harmonic analyzer, and a spectrum analyzer. The DACI and LVDAC-EMS also allow manual and timed data recording. The recorded data can be saved to files in any specified location, graphically represented with the provided graph plotting tool, and exported into a spreadsheet application.

The DACI and LVDAC-EMS can also be used with the Four-Quadrant Dynamometer/Power Supply, Model 8960, to implement a variety of control functions for advanced training in various fields of electricity and new energy, including electric power technology, ac/dc rotating machines, renewable energy, transmission lines, and power electronics.

The DACI performs data acquisition to feed raw signal data to the LVDAC-EMS computer based instruments, and it performs various types of control functions, mainly to control the electronic switches of the IGBT Chopper/Inverter module, Model 8837, or those of the Power Thyristors module, Model 8841.

To activate data acquisition for a specific computer-based instrumentation function, a license for this function must be ordered for each DACI on which the function is to be used. Similarly, to activate a specific control function, a license for this function must be ordered for each DACI on which the function is to be used.

The firmware (program used to run the microcontroller) of the DACI can be upgraded anytime by using the device firmware upgrade (DFU) included with the latest version of LVDAC-EMS available on the Festo Didactic website.
