DCU EKOM-3100 is designed for data acquisition from energy meters, power quality instruments and other digital measuring devices, for time synchronizing in these devices, for keeping energy use archives during different periods, profile archives, sub-intervals, network parameters, autoreading, for registration of digital signals of status of the equipment, output of control signals, processing of data received (including calculation of additional parameters based on user`s algorithms), data storage and translation to upper levels of automated information and measuring systems.
The device has the necessary functionality for building such systems as fiscal smart energy metering systems, technical smart energy metering systems, advanced metering infrastructures, telecontrol systems, data acquisition and transmission systems.
