Abstract

The control circuit is designed to test the contact states of relay contacts connected to an electrical load. A converter element is associated with each contact so as to obtain by force an appropriate electrical load for the contact in question. The converter element is an intermittent operating current supply device. This device which is in series with the contact taps a large part of the current flowing through the contacts and directs it to an exterior circuit. The current supply device is a regulator which increases the output voltage. The power passing through the contact is fed by the current device to the current supply source and or to a separate circuit. [DE2719212A1]
