Abstract: The electronic interface device permits remote control and monitoring of a power distribution panelboard coupled with a management system. In respect of each outgoing power line, a local control unit is connected to a remote control unit while a central unit is assigned to each local control unit to the remote control unit which then converts the data delivered by the local control unit into data which are compatible with the central unit. Exchange of data between each remote control unit and the management system is achieved by at least one microprocessor-based control circuit located in the central unit, through a series link or current loop.
