SIEMENS Clearguard® Phase Shift Overlay(PSO 4000 Series) track circuit provides trackoccupancy information for a train detection system.
The PSO 4000 Series is a reliable and secure,microprocessor based, vital system for use in avariety of complex installations.
The ability of PSO 4000 Series to differentiatebetween its operation signal and all other signalspresent on the track is due to the non-symmetricalcoded modulation and receiver decoding techniqueswhich ensure that the systems is immune to randomor foreign AM, FM and beat signals.
