Schneider Electric (Harmony) – RE22R2KMR – Off-Delay Timer Relay, 24–240 V AC/DC

The RE22R2KMR is a compact off-delay timer relay from Schneider’s Harmony series. It provides an adjustable delay after de-energization (Function K), with a time range from 0.05 s up to 100 min, easily adjustable via a rotary dial. Designed for DIN-rail mounting, it integrates seamlessly into industrial control panels, HVAC systems, barrier controls, and lighting applications.
