The physical design of the DC-TUIO31 allows the active controller module to be inserted or removed without interrupting power or signal connections to the remaining nodes. Field termination wiring remains fully undisturbed during the exchange.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does the DC-TUIO31 support dual-redundant module installations?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e No. The DC-TUIO31 is a 9-inch non-redundant base board. It only supports a single active UIOM card. For redundant, dual-module operations, a 12-inch redundant IOTA (CC-TUIO41) must be deployed.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the operational distinction of the \"DC-\" prefix compared to the \"CC-\" prefix?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e The \"DC-\" prefix indicates that this IOTA is an uncoated module intended for clean, environmentally controlled control rooms.
