A logic circuit produces a direct current signal not exceeding a predetermined maximum intensity at its output terminal regardless of the amplitude of an alternating current signal applied to its input terminal. The circuit includes an AC to DC converter having an output which is non-referenced to ground, a condenser connected between the positive and negative output terminals of the converter, and a constant current generator connected between the positive output terminal of the converter and ground, the negative output terminal of the converter constituting the output terminal of the logic circuit.
