Abstract
A control device includes a relay device coupled to a processor device, a power device coupled to the processor device and the relay device for energizing the processor device and the relay device, and a load device coupled to the relay device. A device may further be used for supplying control signals to the processor device, in order to switch on and switch off the relay device. The relay device includes two transistors coupled to the processor device, and two coils coupled to the transistors, for being actuated by the processor device with less electric power consumed.
