Safety System ProSafe-RS Lite
Safety System: ProSafe-RS Lite
ProSafe-RS Lite conforms to the international safety standard for up to SIL2(*1) application. You can select the ProSafe series from SIL2 (ProSafe-RS Lite), SIL3 (ProSafe-RS) and SIL4 (ProSafe-SLS). Continued functional enhancements to ProSafe series help you run your plants safely.
*1 Established by the International Electrotechnical Commission (IEC), a safety integrity level (SIL) indicates the relative level of risk provided by a safety function. SILs 1 through 4 are defined by IEC 61508. Compared to a plant where safety measures are not in place, at SIL2 the risk factor is reduced to between 1/100 and 1/1,000. At SIL3, the risk factor is in a range between 1/1,000 and 1/10,000. At SIL4, the risk factor is in a range between 1/10,000 and 1/100,000.

ProSafe-RS Lite Safety Instrumented System
ProSafe-RS Lite inherits the highly reliable technology of ProSafe-RS, and by combining with CENTUM VP/ProSafe-RS, enables integrated operation that includes process and safety control. It greatly contributes to your plant’s safety and reliability. As comprehensive SIS vendor, Yokogawa will support your functional safety management entirely throughout the plant lifecycle.
Single-module architecture achieves SIL2
The many SIL2 compliant safety instrumented systems available in the market achieve SIL2 by redundant modules, on the other hand, ProSafe-RS Lite achieves SIL2 with a single module configuration. Building a simpler system means keeping down installation, maintenance, and other running costs. Redundant module configuration of ProSafe-RS Lite enables to maintain SIL2 compliance even if one module fails that achieves high availability.
Integration with control systems
ProSafe-RS Lite can be fully integrated with CENTUM VP Control System and ProSafe-RS. The familiar CENTUM VP monitoring and operation terminal (HMI) allows operators to monitor and control processes, as well as centrally monitor safety instrumented systems installed for emergency shut down, fire and gas, burner management purpose. During plant abnormal condition, you can quickly ascertain the situation by alarms from the safety instrumented systems and take appropriate action.
Easily add SIL2 to existing systems
ProSafe-RS Lite supports the same control bus Vnet/IP(*2) as CENTUM VP and ProSafe-RS. You can easily add ProSafe-RS Lite to existing systems built on the Vnet/IP. The engineering tool for ProSafe-RS also can be commonly used so there is no need to install or learn any new tools.
*2 Vnet/IP is a control network developed by Yokogawa that delivers high reliability and responsiveness, and conforms to the IEC61784-2 international communication standard for the process industry.
