Allen-Bradley 800T-XA N Time Delay Relay

Allen-Bradley 800T-XA N Time Delay Relay is a timing device in Rockwell Automation's 800T family, designed to introduce a controlled delay into control circuits when used with compatible 800T push-button accessories. The "N" designation denotes a contact arrangement that provides one normally open and one normally closed contact in addition to the timing function, enabling straightforward sequencing and interlocking in single-source control panels. As part of the 800T ecosystem, it integrates with Rockwell's 800T and 800H accessories, including contact blocks and shallow blocks, to tailor the operator interface and control logic. Typical applications include delaying activation of a motor starter, sequencing a relay coil with a defined interval, or providing a timed interlock in manual/automatic control loops, where reliable timing and switch action are required in industrial environments.
