Smart Safety Loops. Reliable Process. 
The DeltaV SIS™ process safety system helps increase safety integrity by continuously monitoring the ability of sensors, logic solvers, and final elements to perform on demand, with faults diagnosed before they cause spurious trips. The Smart safety instrumented system (Smart SIS) approach increases process reliability and reduces lifecycle costs.

  Smart SIS – optimized process reliability.

As an extension of the PlantWeb™ digital plant architecture, Smart SIS provides an integrated approach to complete safety loops-from sensor, to logic solver, to final element. As a key component of Emerson's Smart SIS, the DeltaV SIS system shuts down your plant when needed for safety, but keeps it running safely when devices fail. read more

  Modular distributed architecture – flexibility to meet your project needs.

The unique modular, distributed architecture of DeltaV SIS enables you to custom fit the system to your SIS applications. This modularity gives you the capability to meet changing project requirements. The DeltaV SIS architecture is flexible to help provide the safety you want, when you want, where you want. read more

  Integrated but separate – increased visibility into your process.

Using the DeltaV basic process control system (BPCS) with the DeltaV SIS process safety system can deliver the benefits of total integration and total separation without the tradeoffs associated with the two extremes. As an integrated control and safety system (ICSS), the DeltaV SIS and DeltaV systems share the same engineering, maintenance, and operations environment. All safety-related information is easily accessible through familiar and intuitive applications. read more

  Certified function blocks – reduced engineering and complexity.

The IEC 61508-certified SIS function blocks deliver powerful functionality right out of the box, simplifying the implementation of complex SIS applications. No custom code is required to implement common SIS tasks. The result is faster configuration and troubleshooting of SIS logic. read more

  Built for IEC 61511 compliance – simplified safety lifecycle management.

The DeltaV SIS system is built from the ground up for IEC 61511 compliance, providing stringent change management, security management, and documentation tools. The system is certified for use in safety integrity level (SIL) 3 applications without restriction. DeltaV SIS simplifies IEC 61511 compliance, eliminating concerns related to proper implementation. read more
