GE IS420YDIAS1B Logic Solver Components

The IS420YDIAS1B will include 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.

The IS420YDIAS1B is one of the most flexible and commonly engineered protection systems 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.

IS420YDIAS1B requires an understanding of more than traditional instrumentation and control engineering, and 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.
