The Allen-Bradley 700-FSM6UU23-EX is a high-performance timing relay from the Bulletin 700-FS series, specifically engineered for use in hazardous locations where explosive gases, vapors, or dusts may be present. Certified for Class I Division 2 / Zone 2 and Class II/III environments, this multi-function timer delivers precise delay-on, delay-off, interval, and repeat cycle timing control with ±0.5% accuracy. Featuring universal voltage input (24–240V AC/DC), dual SPDT output contacts, and robust IP67-rated housing, it provides reliable time-delay switching in oil & gas, chemical processing, mining, and grain handling facilities where standard industrial timers cannot operate safely. Designed as a direct replacement for legacy electromechanical timers, it combines intrinsic safety compliance with modern solid-state reliability.
