Schneider Electric RE22R1KMR Time Delay Relay

The Schneider Electric RE22R1KMR is a compact off-delay timing relay in the Harmony Timer Relays family, delivering a controlled delay on de-energization for a single Form C (SPDT) contact. It accepts a wide coil supply of 24–240 V across AC or DC and can switch a load rated up to 5 A at 250 VAC through its 1C/O output, making it suitable for panel-wide sequencing and interlock applications. The timing range spans 0.05 seconds to 10 minutes, enabling short interlocks, machine sequencing, or controlled shutdowns in industrial control circuits. Function K denotes Delay On De-energization without an auxiliary supply, meaning timing begins when the control power is removed without needing a separate timer supply. Mounting is via standard DIN rail, allowing easy integration into common industrial enclosures. Widely used in automation tasks where a precise, off-delay is required, the RE22R1KMR provides reliable timing for loads like motors, valves, conveyors, and solenoids while preserving straightforward wiring and compatibility with Schneider Electric's Harmony ecosystem.
