The RSVD-LED signal is a high-pitch (green, yellow and red) LED signal that replaces the decentralized fan signals with shield relay (RSVD) used in railway signaling installations.
The RSVD-LED signal is designed to be fully interchangeable with existing railroad display relay signals and therefore replaceable on both aluminum (RFI category 825/460) and polycarbonate (RFI category 825/462) covers. By means of a single field-configurable device, it is possible to apply all combinations of aspects present in the field. The RSVD-LED is also compatible with all external devices normally installed in the system (flasher, encoder).
The RSVD-LED safely acquires the input signals on the basis of which the correct aspect can be switched on, it also checks the integrity of the LEDs and signals any anomaly through an integrity relay.
The RSVD-LED signal is a device approved by Rete Ferroviaria Italiana and classified SIL4 according to CENELEC EN 50128 and EN 50129 standards.
It complies with RFI specification DTCDNSSSTB SF IS 05 762 A.
