What is a safety instrumented system?:

A recent publication from Schneider Electric highlights that EcoStruxure Triconex Safety and Critical Control has been at the forefront of safety and critical control solutions for four decades. Their Safety Instrumented System (SIS) is characterized by a highly resilient triple modular redundant (TMR) structure, with over 1 billion safe operating hours without a recorded dangerous failure on demand. The integration of Schneider Electric’s TÜV Rheinland-certified SIS into a facility minimizes operational risk and facilitates uninterrupted safe operation.

The SIS is composed of three fundamental components: sensors that identify initiating events, logic solvers that decide the reaction to threats, and final elements that restore processes to a safe condition. Through the execution of safety instrumented functions, an SIS aids in lowering risks to a tolerable level, safeguarding individuals, production, and the environment. EcoStruxure Triconex SIS systems comply with IEC 61508 functional safety standards, guaranteeing adherence to international safety regulations and best practices in process safety management.
