摘要： A device for the command and control of the electric power supply of windings of an electromagnetic actuator, comprising a plurality of electronic means configured to receive at the input either a direct current feeding voltage or alternatively an alternating current feeding voltage and to generate at the output a first digital command signal triggering an activation phase of the electromagnetic actuator in which at least one of the windings is powered, for a first predefined and adjustable time interval, with an activation current, a second digital command signal triggering a maintenance phase of the electromagnetic actuator in which the windings are powered with a maintenance current having an intensity lower than the activation current, and a third digital command signal triggering a third phase of deactivation of the electromagnetic actuator in which the power supply of the windings is interrupted for a second predefined and adjustable time interval.
