Solid State Block

By taking advantage of our state of the art manufacturing wing, we have become a reliable manufacturer, exporter, and service provider of a wide ambit of Solid State Block Proving By Axle Counter (Digital). These products are widely known for absolute accuracy, high durability, competitive prices, best grade materials, ease in changing information, and the likes. Our range of Solid State Block Proving By Axle Counter (Digital) is in compliance with prevailing quality standards of the industry.Salient Features:The SSBPAC (D) is of 2 out of 3 hardware architecture with implementations of the fail safety principles. It complies with the CENELEC standards and conforming to Safety Integrity Level - 4 (SIL-4). The system incorporates auto features and eliminates manual co-operations from other end for Line Clear and Line Close operations. Emergency cancellation at the receiving station. Automatic Train On Line. Automatic Line Close after sequence proved at receiving end and section is free. Simplified Block Back / Block Forward Operations. Cooperative Cancellation. Line Clear Block Key (LCB Key) to prevent automatic granting of Line Clear. Station Master Key (SM Key) to prevent unauthorized panel operations. Fully solid state and relays are only for final vital outputs. Single Line Working with provisions for shunting with shunt key EKT Event logging operations and data storage in built in the system. Data logger network interface. Communication media: (1 pair cable in quad or on voice channel in OFC.) Block bell and telephone on separate pair of quad or voice channel of OFC. Two repeater relays to repeat input status at the other end.Safety Features : Safe shutdown if the output is less restrictive. Mine field in the non-program area for trapping the CPU. Inputs and Outputs are exchanged and validated among 3 CPUs in Inter Processor communication before delivering to independent voter module. Continuous monitoring of system cycle time. In case of deviation safe shutdown of system. 2 Bit bi-state control for all the vital output relays. Continuous monitoring of output for every 50ms. Online Hardware diagnosis and self checking.Advantages: Less maintenance and requires no periodical over-hauling in consideration with the electromechanical systems. It considers signal overlap distance for granting line clear, which is not available in some of the present systems. It has inbuilt data logging capability which logs all the panel operations, events, relays status and other information. All the panel indications are with LEDs. No need for next train on PLC after push back operation.
