The card is designed to support the hot-swapping of individual CHARM modules, allowing for maintenance or replacement without disrupting the primary communication loop of the associated I\/O network.\u003c\/p\u003e\n\u003cp\u003eQ: How does the redundant power architecture function?\u003c\/p\u003e\n\u003cp\u003eA: The module incorporates dual 24 V DC power inputs. In the event of a primary power supply failure, the card automatically transitions to the secondary source to ensure continuous I\/O signal integrity.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Install the SE6504 on the dedicated Electronic Marshalling carrier assembly.
