Concept of Redundancy in Control Systems -

2021-8-21  The Mean time between failures of any system dependent upon certain critical components may be extended by duplicating those components in parallel fashion, such that the failure of only one does not compromise the system as a whole. This is called redundancy.. A common example of component redundancy in instrumentation and control systems is the redundancy offered by
