Safety instrumentation systems can help companies achieve risk reduction and incident prevention. A safety instrumented system (sis) takes automated action to keep a plant in a safe state, or to put it into a safe state, when abnormal conditions are present. The sis may implement a single function or multiple functions to protect against various process hazards in your plant.
