Iec 61496 Wikipedia

IEC 61496 requires that the safety device interface with the machine control system. For Type 4 devices, the standard often requires the use of , sometimes called a "muttest." This is a feedback loop where the ESPE monitors the state of the final switching elements (contactors) to ensure they have actually opened when the safety zone is breached.

While ISO 13849 focuses on the reliability data (MTTFd, DC, etc.) to calculate a Performance Level (PLd or PLe), IEC 61496 dictates the specific design and testing requirements that allow a device to claim compliance with a certain "Type." iec 61496 wikipedia

IEC 61496-5 (In development): Will cover radar devices. Classification of ESPE Types IEC 61496 classifies ESPE into types, which dictate the level of risk the device can manage: Type Suitable for PL (ISO 13849-1) Suitable for SIL (IEC 62061) Common Use Type 2 Up to PL c SIL 1 Lower risk, single-channel/monitored Type 3 Up to PL d SIL 2 Mid-level, often laser scanners Type 4 Up to PL e SIL 3 High risk, dual-channel/self-monitoring Note: As of updates in 2020/2024, Type 2 devices are generally restricted to lower-risk applications, with Type 4 or 3 often required for SIL 2/PL d and higher applications. Key Technical Changes (2020/2024 Revisions) The standard has evolved to accommodate new technologies and tighter safety regulations: Harmonization: The 2020 revision aligns more closely with generic directives and standards (e.g., EMC Directive). Relocation of Requirements: Common requirements for various ESPE types were moved from Part 2 to Part 1. Type 3 Definition: The 2020 revision officially solidified the use of Type 3 for applications up to PL d. Environmental Robustness: Updated mechanical tests define higher shock resistance requirements (up to class 3M7).
