The invention relates to a pulse signal multiplier for providing a secondary pulse signal without reaction from a primary pulse signal of a pulse signal generator, in particular for multiplying a rotational speed sensor signal used in a train safety system, the pulse signal multiplier comprises-an input circuit (120, 120 ') that taps a primary pulse signal via a shielded branch signal line (190), = the input circuit processes an input signal for transmission across an electrically isolated barrier, and = the input circuit is provided with its own electrical shield,-an output circuit (181, 181') that receives the signal transmitted through the barrier, and-an output circuit (182, 183 ') that outputs the signal transmitted through the barrier. The input circuit (120, 120 ') processes the transmitted signal into an output signal, and the output circuit is likewise provided with an own electrical shield (174), and-an optical signal transmission path (382) bridging a barrier between the input circuit (120, 120') and the output circuit (181, 181 '), = the optical signal transmission path is hermetically closed and the electronic signal transmitter (316) and the electronic signal receiver (350) of the optical signal transmission path are arranged within a respective shield (122, 174) of the input circuit (120, 120 ') or of the output circuit (181, 181').
