A circuit arrangement for the time-delayed startup of electronic modules (20) connected to a module carrier (1) comprises a comparator (28) provided with a reference voltage applied thereto and an operating voltage which is applied via charging capacitors (35 to 38) with different capacitances. The terminals (4c-f to 19c-f) for the charging capacitors are integrated in different combinations into the terminals (4a,b to 19a,b) 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.
