Allen-Bradley 700-FSA7UU23 Timing Relay

Allen-Bradley 700-FSA7UU23 is a compact, 22.5 mm-wide DIN-rail timing relay in the 700-FS family that delivers a single-function ON-Delay timing with DPDT (2 Form C) changeover contacts, enabling two independent loads to be controlled from one device. It accepts either 24 to 48 V DC or 24 to 240 V AC power with 50/60 Hz operation, allowing a single module to be drop-in compatible with both DC and AC control circuits in mixed-control panels. The timing range spans from 0.05 seconds to 300 hours, giving the user the ability to implement short delays for sequencing or long intervals for interlocks and timed processes, all within a robust DIN-rail package. With two independent changeover outputs, the unit can coordinate dual actuators, drive separate coils, or implement interlock schemes without requiring additional relays, which helps reduce panel space and part count. As part of Allen-Bradley’s 700-FS family, this relay is a common choice for motor-start sequencing, conveyor timing, and other time-based control tasks in industrial automation where repeatable, deterministic delays are essential.
