Allen-Bradley 800T-XA Time Delay Relay Module

Allen-Bradley 800T-XA is a contact block accessory for the 800T family of time-delay relays and pushbutton assemblies, providing a single Form C contact configuration with one normally open (N.O.) contact and one normally closed (N.C.) contact. This auxiliary block complements timing circuits by delivering an additional dry-contact output for signaling, interlocking, or feedback, while the 800T timer function remains separate. Designed to mount with 800T pilot devices, the 800T-XA extends the control logic capability of the 800T system without introducing timing itself, making it a common choice in machine control panels where a timer’s output needs a paired contact state for sequencing or safety interlock logic.
