A control device for a conveyor device, comprises a control unit adapted to generate control signals for a conveyor device, a data interface adapted for signal transmission of control signals to the control unit, a first power interface adapted for power supply to the control unit, a connection interface adapted for establishing a signal control connection and a power supply connection between the control unit and a conveyor device located outside the control device. A second power interface is adapted to supply power to the control unit, the first interface being adapted to receive a power supply in the form of a power supply with a first voltage, the second interface being adapted to receive a power supply in the form of a power supply with a second voltage or, instead of the second voltage, with a third voltage whose level is different from the level of the second voltage.
