The IS410STCIS2A IS400STCIS2AFF will consist of three types of components, including a sensor component, a logic solver component, and a final control element. Together, these components form a safety instrumented system (SIS) that detects uncontrolled process conditions and automatically restores the process to a safe state, regardless of the functionality of the underlying process control system. In this case, the SIS may include programmable systems or non-programmable systems.

IS410STCIS2A IS400STCIS2AFF is one of the most flexible and commonly engineered protection systems available in process plants today. According to current practice, the design of an SIS is a risk-based process in which the selected equipment and associated maintenance and testing procedures are customised to the specific requirements of the application. This risk-based approach produces superior designs that reduce the required risk while minimising cost.

IS410STCIS2A IS400STCIS2AFF Requiring an understanding of more than traditional instrumentation and control engineering, SIS design has become a more complex process. In addition to the basic concepts, SIS design requires expertise in analysing the risks of the controlled process (which inevitably requires an understanding of the process) in order to establish the design objectives, and expertise in reliability engineering to ensure that the selected objectives are met.
