ISO 13849 Common Cause Failure comparison showing independent failure versus one common cause affecting redundant safety channels

ISO 13849 Common Cause Failure Explained – CCF and the 65-Point Assessment

By

ISO 13849 Common Cause Failure Explained – CCF and the 65-Point Assessment Redundancy is an important design principle in many safety-related control systems. Two independent channels can help ensure that a single component failure does not lead to the loss of the safety function. However, redundancy only provides the intended benefit if both channels are …
