摘要:
The control device (1) comprises a piloting circuit (10) for the electroactuators (2) and a timing circuit (8) which generates timing signals (T) supplied to the piloting circuit (10) for control of the electroactuators (2). The piloting circuit (10) has a first and a second input terminal (12, 14) which are connected in use respectively to a first and a second terminal of an electrical energy source (16), and a plurality of pairs of output terminals, one for each electroactuator (2); each pair of output terminals comprising a first and a second output terminal (18, 20), between which a respective electroactuator (2) is connected in use. The piloting circuit (10) comprises a plurality of control circuits (30), one for each electroactuator (2), which receive as input the timing signals (T) and are activated selectively by the timing signals (T) themselves. Each control circuit (30) comprises a first transistor (34) which is connected between a respective first output terminal (18), and, at least in pre-determined operating conditions, the first input terminal (12) of the piloting circuit (10); a second transistor (36) connected between a respective second output terminal (20) and the second input terminal (14) of the piloting circuit (10); and a diode (38) which is connected between the respective first output terminal (18) and the second input terminal (14) of the piloting circuit (10) itself.
