ProSafe-SLS

Yokogawa is the world’s most experienced safety and control firm. Our commitment to providing reliable, state of the art safety instrumented systems is rooted in a wealth of installations since 1962.

The solid-state, hard-wired ProSafe-SLS covers all requirements in process industries. The product line covers specific requirements for individual safety instrumented systems and offers all safety integrity levels (SIL 3-4) for the oil & 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 together with ProSafe-RS safety system as well as FAST/TOOLS SCADA software package.

Safety-by-design

The ProSafe-SLS is a Safety Instrumented System that was designed for applications, which require the highest Safety Integrity Levels (SIL 3 & 4).

It employs solid-state elements to process the functional logic. This technology is capable of executing all typical Safety tasks, as well as the related supplementary Non-Safety-Critical functions. This comprises interfacing with a Human Machine Interface, Process Control System, Sequence of Event Recording system, SCADA system, etc.

The sophisticated design and superior Safety performance have created the Safety reference standard for solid-state Safety Instrumented Systems.

A radical Safety achievement, is the elimination of software for an operating system and for self-diagnostics. Instead, a unique inherent self-test technology is employed, throughout all Safety-related parts of the ProSafe-SLS system.
