Safety Instrumented Systems (SIS) consists of an engineered pairing of a valve, an actuator and controls which are to be used on critical process systems.
A SIS is engineered to perform specific control function, to failsafe or maintain safe operation of a process when unacceptable or dangerous conditions occur. The specific functions performed by an SIS are integrated into a logic solver or control system to produce a safe state condition for personnel, equipment, process, and the environment.
Many international specifications govern the application of an SIS, requiring the series of equipment to function properly. The critical selection of all equipment must meet demanding criteria and mean time between failure ratings.
