This versatility ensures that it can meet diverse operational needs while maintaining high efficiency and safety standards.

ProSafe-RS Lite adheres to the global safety standard suitable for applications up to SIL2. The ProSafe series offers options across SIL2 (ProSafe-RS Lite), SIL3 (ProSafe-RS), and SIL4 (ProSafe-SLS), ensuring flexibility in safety measures. Ongoing improvements to the ProSafe series are designed to enhance the safety of plant operations. The concept of safety integrity level (SIL) was established by the International Electrotechnical Commission (IEC) and measures the effectiveness of safety functions, classified into four levels from SIL1 to SIL4 as outlined in IEC 61508. When compared to environments lacking safety protocols, SIL2 dramatically lowers the risk factor to between 1 in 100 and 1 in 1,000. At SIL3, this risk factor decreases further, ranging from 1 in 1,000 to 1 in 10,000, whereas SIL4 achieves an even lower risk factor, between 1 in 10,000 and 1 in 100,000. ProSafe-RS Lite benefits from the proven reliability of ProSafe-RS technology, and its integration with CENTUM VP/ProSafe-RS facilitates a cohesive approach to both process management and safety oversight. This synergy not only enhances operational efficiency but also reinforces the commitment to maintaining high safety standards in industrial settings.

The ProSafe-RS safety instrumented system is certified by TÜV for use as a Safety Instrumented System (SIS) across SIL 1, 2, and 3 applications within a single modular setup, while offering enhanced availability in a redundant configuration. This system can function independently or be seamlessly integrated with the CENTUM VP Distributed Control System. Yokogawa’s industrial safety solutions ensure minimal disruptions through dependable protection across all SIL levels, featuring real-time dashboards that evaluate present and potential risks, along with virtual scenario testing to analyze the effects of prospective bypasses and overrides. Additionally, the system supports online modifications, enabling continuous operation during upgrades, automated compliance reporting to enhance testing intervals, and comprehensive service and lifecycle support. As the crucial last line of defense, the safety controller is designed for reliable performance precisely when needed. Furthermore, Yokogawa's unique Versatile Modular Redundancy ensures sustained SIL 3 operation even amidst multiple failure scenarios, highlighting the robustness of the system's design. This adaptability is essential for maintaining safety and operational efficiency in complex industrial environments.

ProSafe-SLS is Yokogawa's advanced, hard-wired safety instrumented system engineered to fulfill the most stringent safety integrity standards. This product line caters to the precise needs of various safety instrumented systems, providing all safety integrity levels (SIL 3-4) across sectors such as oil and gas, petrochemicals, chemicals, nuclear, and conventional power generation. Additionally, the ProSafe-SLS system seamlessly integrates with Yokogawa's CENTUM VP process control system and the FAST/TOOLS SCADA software suite. Its modular architecture enables the creation of diverse applications, ranging from compact HIPS systems to extensive ESD and F&G systems, all while ensuring rapid response times to meet any process requirements. Designed specifically for scenarios necessitating top-tier Safety Integrity Levels (SIL 3 and 4), the ProSafe-SLS utilizes solid-state components to execute its functional logic efficiently. This combination of features makes ProSafe-SLS an optimal choice for industries where safety is of paramount importance.

Despite reductions in both capital and operational expenditures, contemporary operators are tasked with minimizing unexpected downtime while ensuring adherence to the functional safety standards outlined in ISA84/IEC 61511. Is your facility equipped to effectively monitor data pertinent to safety system performance and regulatory compliance? Throughout the entire lifecycle of a plant, Yokogawa’s Sustainable Functional Safety Management (FSM) solution consistently evaluates all demands for safety actions and any failures in process operations against established Safety Performance Indicators. This ongoing assessment provides timely safety performance updates to all personnel on-site, which is essential for operational efficiency. Moreover, proactive management of safety information facilitates continuous adherence to IEC 61511 and ISA84 throughout the entire lifespan of the asset. After completing the safety instrumented system (SIS) design and layer of protection analysis (LOPA), the setup for monitoring process safety is streamlined through automation. Additionally, our sustainable FSM solution enhances efficiency by automating change management processes, ensuring that safety protocols are not only maintained but also improved over time.
