yokogawa-ProSafe-RS Lite
Overview
The Yokogawa ProSafe-RS Lite is a safety instrumented system that conforms to the international safety standard IEC 61508 for applications up to Safety Integrity Level 2 (SIL2). It provides dependable safety shutdown and emergency protection functions for process plants that require certified safety logic without the full scope of a SIL3 system.
ProSafe-RS Lite is part of the scalable ProSafe series, which includes ProSafe-RS for SIL3 applications and ProSafe-SLS for SIL4 applications. This consistent product family allows plants to select the safety integrity level appropriate to each safety function while maintaining a common engineering environment.
Engineering & Design
The ProSafe series continues to receive functional enhancements, helping plants run safely while adapting to evolving requirements. The safety integrity level indicates the relative risk reduction provided by a safety function: at SIL2 the risk factor is reduced to between 1/100 and 1/1,000 compared to a plant without the safety measure, while SIL3 reduces it to between 1/1,000 and 1/10,000 and SIL4 to between 1/10,000 and 1/100,000.
ProSafe-RS Lite shares the engineering and operational concepts of the ProSafe-RS platform, allowing integration with Yokogawa control systems and a consistent approach to safety lifecycle management across the plant.

Why Seven Star LLC
Seven Star LLC supplies Yokogawa ProSafe-RS Lite safety system components for safety instrumented system projects across the Gulf, with verified specifications and engineering support. Our team assists with safety system spares, module selection, and expansion of existing ProSafe installations.
We support oil and gas, petrochemical, and power plants with reliable B2B supply of safety system hardware and documentation throughout the GCC.
Safety Lifecycle Support
The IEC 61508 conformity of ProSafe-RS Lite simplifies the documentation burden of safety lifecycle management, because the safety integrity claims are backed by the system’s certification. This supports the verification and validation activities required at each phase of a safety project.
Because ProSafe-RS Lite is part of the wider ProSafe family, plants can standardise engineering tools and operator training across SIL2 and SIL3 systems, reducing the cost and complexity of maintaining different safety platforms.
Documentation & Supply
Seven Star LLC supplies Yokogawa ProSafe-RS Lite components with technical documentation and support for module selection, spares planning, and system expansion.
Our specialists assist safety engineers with the hardware and documentation needed to keep safety instrumented systems running reliably.
The ProSafe-RS Lite platform is frequently applied where the safety function requires SIL2, such as simpler ESD and fire and gas functions, while the same engineering environment scales upward for SIL3 duties. This scalability protects the plant’s investment because logic can migrate between platforms without retraining the engineering team.
Safety projects benefit from a supplier that understands the documentation burden, and Seven Star LLC supports the records needed for safety lifecycle compliance.
The common engineering environment shared with ProSafe-RS also means that operator displays, alarm handling, and diagnostic tools remain consistent as the safety system portfolio grows.
