S+ Safety: functional safety up to SIL3

Safety for people, environment and equipment is a nonnegotiable priority, and a power plant automation system must ensure that this priority is supported by the right technology and application knowledge.

ABB can meet the challenge on both fronts thanks to S+ Safety and to a dedicated team of qualified functional safety engineers trained specifically to deliver solutions meeting the highest safety expectations. 

S+ Safety provides a Safety Integrated System (SIS) functionality that is TÜV certified based on relevant standards such as IEC 61508, IEC 61511, NFPA 85. The Safety Integrated Level (SIL) of the equipment is 1-3. The basis for S+ Safety is the proven-in-use, fail-safe solution based on 800xA High Integrity.

With the S+ Safety solution, it is possible to implement functional safety applications that are planned with and executed by Symphony Plus. Thanks to the redundancy option (quad redundancy configurations), it is possible to provide an SIS with the highest availability values (99.9999%).

The product offering is complemented by a portfolio of services including asset and safety lifecycle, safety consultancy, SIL assessment, software and hardware technologies, and maintenance support.

Why ABB?

  • Over 30 years of experience in functional safety through SIS
  • SIL 1 to SIL 3
  • High availability through redundancy option
