DeltaV™ Safety Instrumented System (SIS)

A Safety Instrumented System (SIS) continuously monitors critical process conditions and automatically takes action when unsafe conditions are detected. Emerson’s DeltaV SIS solutions help protect personnel, equipment, and the environment while reducing unplanned shutdowns and improving overall process availability.

• An integrated control and safety system creates a unified environment for engineering, operations, and maintenance. With a common engineering environment and operator interface, daily operations and maintenance are streamlined. Operators and engineers can use the same tools and procedures for both control and safety functions, reducing the training curve and minimizing the risk of errors.

• Improved Asset and Event Management: Integrated systems allow for easier time synchronization and better management of assets and events, which can help minimize unscheduled downtime and improve overall equipment efficiency (OEE).

• Enhanced Diagnostics and Reduced Nuisance Trips: Modern integrated solutions provide improved diagnostics, which help minimize nuisance trips and improve process and personnel safety.

• Unified Security Management: Integrated-yet-separate architectures can share some security layers, simplify management while still maintain independent, SIS-specific protections. This includes features like unique locking mechanisms for logic solvers and management of change solutions.

DeltaV SIS offers tools such as DeltaV AgileOps that continuously monitor the health and status of safety functions, bypasses, and interlocks. This allows operators to identify degraded safety conditions, verify safety loop performance, and maintain confidence that protection systems are functioning as intended.

Emerson’s DeltaV Safety Instrumented Systems (SIS) are used across all process industries for process and emergency shutdown systems, burner management systems, fire and gas systems as well as pipeline. These solutions help organizations meet functional safety requirements, protect critical assets, and support reliable production in demanding operating environments.

DeltaV SIS with Electronic Marshalling uses certified function blocks, common engineering tools, and fit for purpose safety logic to reduce configuration complexity. By utilizing out-of-the-box functionality and streamlining implementation, organizations can reduce the risk of human error, improve troubleshooting efficiency, and help prevent unnecessary process trips.
