The CC-TDOB11 features a conformal coating on its components and trace layout, making it robust enough for harsh, corrosive atmospheres (ISA Class G3).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ:\u003c\/strong\u003e Can this 6-inch IOTA board support a redundant pair of digital output modules?\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA:\u003c\/strong\u003e No. The DC-TDOB11 is configured strictly as a non-redundant (Non-R) board, housing only one plug-in card socket. Redundant card architectures require a 12-inch IOTA module with dual card sockets.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ:\u003c\/strong\u003e What happens to the outputs if the main controller module is hot-swapped off the IOTA?\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA:\u003c\/strong\u003e Since this is a non-redundant configuration, removing the plug-in digital output card will immediately drop power to all 32 channels, forcing all connected field devices to their de-energized safe states.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTS35 DIN-Rail Mounting:\u003c\/strong\u003e Secure the IOTA carrier directly onto standard TS35 DIN-rail.
