Abstract
The invention relates to a relay controller for controlling an excitation current of a relay, wherein the relay controller is designed, upon the energization of the relay by means of a switch, to control the excitation current through the excitation winding of the relay in such a way that through the excitation winding there flows firstly a pull-in current and, after a pull-in time has elapsed, through the excitation winding there flows a holding current that is lower than the pull-in current, and wherein the relay controller is designed, upon the switching-off of the relay by means of the switch, to feed a commutation current that flows through the excitation winding to the commutation device through the first terminal and through the second terminal of the relay controller.
