Iec 61496-1 Pdf (2024)

One of the most critical aspects of IEC 61496-1 is its classification system for ESPEs, known simply as "Type 2" and "Type 4". These types are fundamental in determining the suitability of a safety device for a given level of risk:

IEC 61496-1 historically categorized devices into (Type 2, Type 4, etc.) which align closely with the Safety Integrity Levels (SIL) of IEC 62061 and Performance Levels (PL) of ISO 13849-1.

| Type | Key Characteristics | Designated Use (Highest Level) | Maximum SIL / PL | | :--- | :--- | :--- | :--- | | | Employs a periodic test to reveal failures to danger. | Applications with lower risk, such as low-speed conveyor belts or packaging equipment where there is no risk of major injury. | SIL 1 / PL c | | Type 3 | Monitors output signals and uses a cross-checking design that tolerates a single fault without loss of safety function. | Medium-risk applications, including plastic injection molding machines, standard machine tools, and automated logistics sorting equipment. | SIL 2 / PL d | | Type 4 | Designed so that a single fault does not lead to the loss of the safety function; it features redundant circuitry and comprehensive fault tolerance. | High-risk applications requiring the highest level of safety integrity, such as high-speed presses, complex robotics, and large-scale industrial machinery. | SIL 3 / PL e | | Type 1 | Designed using simple components without complex fault detection. | Low-risk applications where a fault is unlikely to lead to a dangerous situation. | SIL 1 / PL c |
