Only Emerson's smart safety instrumented system (SIS), an extension of the proven PlantWeb® digital plant architecture, uses digital intelligence and diagnostics from sensor to logic solver to final control. This integrated approach offers automated safety-loop testing and advanced diagnostics that increase system availability while reducing life-cycle costs and facilitating regulatory compliance.

You're responsible for ensuring that your plant complies with IEC 61511, Safety Instrumented Systems (SIS) for the process industry sector. Yet you still need to maximize profitability, which means reducing costs while maintaining flexible production levels. Is all this possible? It is, when you choose instrumentation from Emerson Process Management. Rosemount® and Micro Motion® instrumentation enables you to meet your safety requirements and make the best decision for your business to help improve your bottom line.

IEC 61511 recognizes two methods for qualifying sensors for use in SIS applications: certification to IEC 61508 or use of sensors with a proven history of safe operation (prior-use). With either option, Emerson is here to support your SIS sensor decision.

The DeltaV SIS system includes a scalable logic solver, integrated configuration software, and embedded digital communications - plus AMSٙ Suite: Intelligent Device Manager software to document and archive instrument configurations and changes.

Emerson's Rosemount and Micro Motion sensors' stability and reliability will lower cost and increase uptime through improved performance, simplified compliance, simple proof-tests, and ease of use.

Final Control Elements utilizing Bettis®, Hytork®, and FieldQ® pneumatic valve actuators and Fisher® FIELDVUE® digital valve controllers provide diagnostics to extend proof-test intervals while delivering high reliability and safety. SIL-PAC integrates these elements and more into a complete SIS Final Control Solution from one source, Emerson.

With expertise proven in safety projects around the world, our professional safety personnel and service teams can help you comply with safety standards and make the most of your smart SIS throughout its life cycle.

For those choosing the prior-use methodology, demonstrating a history of safe operation is paramount. As the world's most preferred sensors, Rosemount and Micro Motion devices have billions of safe operational hours supported by third-party documentation. You now have the confidence and documentation needed for installing transmitters in your safety systems.
