Allen-Bradley 800T-D Terminal Block DIN Rail Mount

Allen-Bradley 800T-D Terminal Block DIN Rail Mount is a two-pole terminal block in the 800T family designed for DIN-rail installation in industrial control panels. It relies on plug-in 800T contact blocks to provide its switching contacts, with observed configurations such as 800T-D1LA1 delivering 1 normally closed and 1 normally open contact using the standard 800T-XA1 block, and 800T-D1AV delivering 1 normally open and 1 normally closed contact using the PenTUFF low-voltage 800T-XAV block. The modular design lets technicians pair the DIN-rail base with compatible contact blocks to match the required logic signals, interlock schemes, or alarm circuits, while the DIN-rail mounting simplifies install and field replacement in crowded panels. Because the base block is configured via the attached contact block, the exact electrical characteristics and footprint depend on the chosen contact block; verify compatibility with 800T-XA1 or 800T-XAV and consult the official catalog for the latest guidance. Common applications include control panels, signaling or interlock circuits, and two-pole signaling paths in automation environments where reliable contacts are required.
