ABSTRACT:
The invention relates to a method and an arrangement for selective driving of valves of small drive power by means of light. A control generates control signals which are modulated onto a light source which emits said control signals which are received by all the valves via solar cells. However only the addressed valve is switched. No cabling is necessary between the control and the valves.
