ABSTRACT:
The invention relates to an electronic circuit arrangement for triggering excitation windings of electromagnetic components, provided with supplementary circuit elements, in particular free-running circuit elements, preferably solenoid valves (MV.sub.1 to MV.sub.n), whereby in order to provide a flexible open-loop control, the components are each connected in series to a controllable contact element (3). To reduce the degree of complexity of the circuit, the manufacturing price and the space requirement, it is proposed that the connecting terminals (1, 4) of this series connection lead directly, and the connections (2) between the components (MV.sub.1 to MV.sub.n) and the contact elements (3) lead via diodes (D.sub.1 to D.sub.n), respectively, to a collecting point (A, B, C), to which collecting points (A, B, C) is linked one and the same supplementary circuit-element configuration (T.sub.F,C.sub.L,10,11) shared by all components. Accordingly, the component parts of the supplementary circuit elements are subject to multiple use; they are available to all of the electromagnetic components.
