Level crossing protection system RLC23 central device
Level Crossing Protection System RLC23 Central device is a modular solution for all types of level crossings. The unique PC application enables configuration of different requirements related to the functionality of the system and to the operation of the external protection elements of a level crossing.
Modular system based on the in-house microprocessor platform consists of two independent subsystems A and B.
Configurable and adjustable safety structure of each subsystem: 2-out-of-2.
The system is developed and certified according to standards EN 50126, EN 50128 and EN 50129 for the highest safety integrity level SIL4 as well as EN 50125-3 for outdoor conditions and EN 50121 -4 for EMC. RLC23 is assessed and certified by TUV Rheinland.
One system has a possibility of driving up to 8 road signals (light + sound); 2 pairs of barriers or half-barriers, functioning independently in time; up to 8 control signals for the train driver.
A remote control unit in the nearest station is an integral part of the RLC23 system, it communicates with the main platform on the level crossing over the DSL (1 or 2 twisted pairs) or optical cable.
The possibility of connecting up to 4 RLC23 devices in one remote communication control network.
Interface with any type of station interlocking system (relay or microprocessor based) is provided in the station on the remote control unit.
The possibility of connecting the automatic block (relay or microprocessor based) through DSL (1 or 2 twisted pairs) or optical cable to the indoor equipment.
Each signal is monitored by both subsystems.
Hot-swap of modules for power-on replacement of modules without safety degradation of the system.
The possibility of remote diagnostics and failure notifications via SMS or e-mail. According to error codes displayed on the screen accurate diagnostics is possible.
