Schneider Electric Harmony RE22 Modular Multifunction Timing Relay
The Schneider Electric Harmony RE22 Modular Multifunction Timing Relay delivers precise, high-performance timing control for industrial automation and machinery applications. This compact 22.5 mm wide DIN-rail-mountable device features an extensive multifunction capability, providing up to 10 distinct time delay functions—including Power On-Delay, Off-Delay with control signal, Interval, and Symmetrical Flashing—all selectable via convenient front-panel rotary dials.
Designed for universal compatibility, it operates reliably across a wide input supply range of 12V to 240V AC/DC.Its dual Changeover (2 C/O, SPDT) configuration allows the second output to be toggled between a standard timed contact or an instantaneous contact for specialized system sequencing.With high diagnostic visibility via built-in LED backlight status pointers, the Harmony RE22 simplifies troubleshooting, shortens commissioning times, and ensures robust equipment protection across HVAC, water segment, and factory automation systems.
