RD Differential Detector

RD Differential Detector The Differential Detector (RD) measures the True RMS current absorbed by the lamp of the Colour Light Signals Italian SDO type and excites an external relay called KS (typical Italian FS 58 type), only if the measured RMS current value is...

REDI Electronic Track Relay

REDI Electronic Track Relay REDI is used in Signalling Systems (IS), in particular to signal occupied/unoccupied track circuits. REDI (Cat/Prog 825/407, 825/421) complies with the RFI DTCDNSSSTB SR 21 028 C Italian Railways Specification. It is mechanically and...

RME for SSE energy Measurement recorder

RME for SSE Energy Measurement Recorder The RME-SSE measures and records the electrical energy supplied by the Electrical Sub-Stations (SSE) to the Overhead Line (TE). The energy value is recorded at settable time intervals (typically every 5 sec) on an extractable...

GSM-R Modem

GSM-R Modem The purpose of IF_GSM-R Modem is to create a data network on the GSM-R channel (Railway) between one or more devices, typically diagnostics devices (MTR, RCE, URD, SMCV, etc.), and a Control Center with the possibility to manage such devices by remote....

DRED Delay Device

DRED Delay Device The Retarding (also called DRED), is a device capable of applying or removing the power supply to a relay connected to its output, after a pre-set time. The DRED guarantees a high level of reliability in typical railway signalling environments...
