Yokogawa ProSafe-RS is a safety instrumented system (SIS) specifically engineered for high-integrity process protection. The architecture is based on a SIL3-certified redundant design, featuring specialized safety control units (SCP461) and safety I/O modules (SDV144). Technical characteristics include the use of Vnet/IP for seamless integration with CENTUM VP, self-diagnostic circuitry, and SNT10 network modules for safety communication. Functionally, ProSafe-RS handles Emergency Shutdown (ESD) and Fire and Gas (F&G) logic, ensuring that hazardous process conditions are safely mitigated. Its non-interfering communication with the DCS allows for a unified operation environment while maintaining the strict independence required for international safety standards.
