Safety Instrumented System: An SIS is also known as a trip and alarm system, emergency shutdown system (ESS), safety shutdown system, safety interlock system, and safety related control system. The SIS is present in case the operator or process control system fails to maintain operations within the safe operating zone. Often, the process alarm alerts the operator to changes in temperature or pressure, and if the operator is unable to address the issue, the SIS takes control and automatically shuts down the system before anything becomes unsafe. The SIS is a layer protecting industrial process systems from further damage in case of process deviation. An SIS is the integration of multiple safety integrated functions (SIFs), one of which typically includes a set of components, such as sensors, logic solvers, and control valves.
