Electromagnetic Compatibility (EMC) in Functional Safety: Standards, Practices, and Compliance

Introduction: Why EMC Matters in Safety Systems In today’s complex industrial systems, electronic and programmable systems are central to executing Safety Functions. However, these systems are susceptible to electromagnetic interference (EMI), which can compromise their reliability and lead to unacceptable risks. Functional safety standards—such as IEC 61508—require that Safety-Related Systems (SRS) demonstrate sufficient immunity to […]
