High-frequency channel-to-channel isolation within the connected I\/O termination assemblies relies on the clean DC power delivered by this unit to prevent cross-talk and ground loop propagation. The filtered power output ensures that low-level FOUNDATION Fieldbus communications and analog signal scaling remain unaffected by incoming AC line transients or industrial electromagnetic interference.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the FC-PSU-UNI2450 be deployed in a redundant N+1 power configuration?\u003c\/p\u003e\n\u003cp\u003eA: Yes.
