Relay protection safety level classification standard
IEC62061 is a specific standard for the machinery part in the IEC61508 standard, encompassing the entire safety chain of machinery equipment. Like IEC61508, it stipulates Safety Integrity Levels (SIL) that can be divided into 3 levels within the machinery field: SIL1, SIL2, SIL3. Either subsystems or their protective equipment, or both, as well as their components, shall be designed, constructed, selected, assembled, and combined in accordance with relevant. Determining the Required Performance Level (PLr) is a fundamental step in ensuring functional safety and reducing machine-related risks to an acceptable level. Protection relays are essential devices used to detect abnormal conditions in electrical circuits.
