The main objective of Functional Safety is to eliminate non-tolerable risks present in a system in order to ensure the safety of people, infrastructure, and the environment. To achieve this, control systems that are independent of the Basic Process Control System (BPCS) are used, such as Safety Instrumented Systems (SIS), with the purpose of automatically bringing the process to a safe state when critical operating conditions occur.

SIS are composed of Safety Instrumented Functions (SIF) that achieve a Safety Integrity Level (SIL), generally established through a Layer of Protection Analysis (LOPA). In general, SIFs are composed of sensors to detect critical conditions, logic solvers to determine the action that must be taken, and final elements that execute the desired action.

The design of these systems must take into account a series of crucial factors for their proper operation. For this reason, Pryxida TECH offers the following detailed studies that provide the client with all the necessary elements to ensure the best performance of this critical system in industrial processes.
