Abstract
A circuit arrangement for the time-delayed startup of electronic modules () connected to a module carrier () comprises a comparator () provided with a reference voltage applied thereto and an operating voltage which is applied via charging capacitors (to) with different capacitances. The terminals (-to-) for the charging capacitors are integrated in different combinations into the terminals (to) on the module carrier for the operating voltage. The startup time-delay is determined on the basis of the different time intervals resulting from the different values of the capacitances and lasting until a voltage exceeding the reference voltage is achieved, whereupon the respective electronic module is connected to the voltage source by means of the comparator in a time-delayed manner.
