Level Crossing Protection
RLC23
Details
RLC23 level crossing protection system is a 2-out-of-2 SIL4 certified system. ALTPRO is producing all system components (central device, train detection, barriers and signals) which enables the Customer maximum flexibility. RLC23 is a highly configurable system and can be easily adapted to any requirement set by the Customer.
RLC23 system provides light, sound and/or physical protection to a level crossing site. Its high configurability possibilities are provided through unique PC application – time parameters, number of outdoor units controlled, different info to be received by the interlocking… The RLC23 central device can be adapted to virtually any LED or driver’s signal available on the market. The range of other system functionalities enables RLC23 to meet various requirements.
Technical Highlights
- Modular system based on the in-house microprocessor platform consists of two independent subsystems A & 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.
