The DeltaV SIS Difference

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


  Standalone or Integated – achitecturally independant safety system.

The DeltaV SIS power supplies, communication channels, hardware and real-time operating systems are physically separate and independant of the basic process control system (BPCS). This maintains the separation required by IEC 61508 and IEC 61511 standards. DeltaV SIS automatically monitors, controls and collects safety-related data.

  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
