AADvance Control System

ProSafe-SLS is Yokogawa's solid-state, hard-wired safety instrumented system designed to meet the highest safety integrity requirements. The product line meets specific requirements for individual safety instrumented systems and offers all safety integrity levels (SIL 3-4) for the oil and gas, petrochemical, chemical, nuclear and conventional power industries. ProSafe-SLS safety instrumented system is also fully integrated with Yokogawa's CENTUM VP process control system as well as the FAST/TOOLS SCADA software package. The modular design of the ProSafe-SLS safety system allows for building all kinds of applications, ranging from small HIPS systems to large ESD and F&G systems while maintaining the fastest possible response time to follow any process demand. The ProSafe-SLS is a safety instrumented system that was designed for applications that require the highest Safety Integrity Levels (SIL 3 & 4). It employs solid-state elements to process the functional logic.

The ProSafe-RS safety instrumented system is a TÜV certified Safety Instrumented System (SIS) for use in SIL 1, 2, and 3 applications in a single modular configuration, with superior availability in a redundant configuration. It can be a standalone system or tightly integrated with our CENTUM VP Distributed Control System. Yokogawa industrial safety systems minimize interruptions with highly reliable protection at all SIL levels, real-time dashboards, quantifying current and future risks, and virtual scenario testing to assess the impact of future bypasses and overrides. Online modification, which allows plants to continue to run during upgrades, automated compliance reporting to optimize testing frequency, and cradle-to-grave service and lifecycle assurance. As the last line of defense, the safety controller must act reliably exactly when it needs to. Yokogawa's exclusive Versatile Modular Redundancy maintains unlimited SIL 3 operation even under multiple failure scenarios.
