Abstract:
A control device comprising:a processor unit, means for supplying control signals to said processor unit, a relay unit coupled to said processor unit, a power unit coupled to said processor unit and said relay unit for energizing said processor unit and said relay unit, a load unit coupled to said relay unit, for being switch on and switch off by said relay unit with the control signals supplied to said processor unit by said supplying means, and said relay unit including a first and a second transistors coupled to said processor unit, for being actuated by said processor unit, said first transistor of said relay unit being actuateable by said processor unit to switch on said load unit, and said second transistor being selectively actuateable by said processor unit to switch off said load unit when said first transistor of said relay unit is not actuated, for decreasing consuming of electric power.
