Safety Instrumented System (SIS)

Safety Instrumented System is a system of hardware and software controls engineered to perform "specific control functions" in order to prevent or mitigate hazardous events by taking a process to a safe state when predetermined conditions are violated. What and how the system should perform may be determined via HAZOPS (Hazard and operability studies) or LOPA (layers of protection analysis).

aeSolutions' engineering specialists will design, configure, test, and install documented Safety Instrumented Systems that verifiably meet the client's Safety Requirements Specifications.
