A connecting device for an electrical installation system for controlling consuming devices and/or for redirecting status signals over a data line with serial digital data transfer on an external bus line. The control and status signal information are passed through a bus coupling unit in a base module to a microcontroller of the base module. The microcontroller of the base module passes information and controls function-specific expansion modules with digital and/or analog inputs and/or outputs for the respective consuming devices. The base module and the expansion modules are connected in an internally communicating manner with the base module, the connection including an internal data bus interconnecting the microcontroller of the base module with microcontrollers of the expansion modules. Additionally, connector device are provide for interconnecting line power from the base module to and through the expansion modules.
