This three aspect LED searchlight with position and brightness control has been designed to be used in railway signalling schemes where the interlocking circuitry has been designed in accordance with S.Se3a, S.Se4a, S.Se5a, S.Se6a standards, in systems where the control of the signal is performed by disc relays. The product can be used for main signals (approach departure or warning signals), and is capable of providing three different coloured light beams from one aperture and can be used with the existing halogen lamp signal housing.
It is very similar to existing systems in use and consists of a power supply unit (GACS-RSVC), and an Optical Unit (GOCS-RS) which replaces the relay interface. The use of this product requires the use of the URRC module. The GACS RSVC acquires the operating voltage and, depending on the polarity, it determines which aspect to be lit. In addition to producing a light beam in accordance with the specific luminosity and chromaticity characteristics, the GOCS-RS module also checks integrity of the light source (optical feedback) and whenever there is an abnormality it generates an alarm (cancel relay disk drive) to the interlocking system without affecting the signal aspect. Compared to the electromechanical system currently in use, all possible combinations of signal aspects can be realised with a single GACS RSVC + GOCS-RS assembly.
In terms of power supply and control circuits, the product is compatible with all types of disk relays currently in use on most signalling schemes, and can be used with static and electro-mechanical flasher units.
