Description
The Schneider Electric RE11RMXMU and RE17xx series are DIN-rail mounted multifunction / time delay relays from the Zelio™ Control range, designed for industrial timing, pulse generation, flasher, and delayed switching applications. The RE11RMXMU is a compact 17.5 mm wide multifunction relay with 8 timing functions (On-delay, Off-delay, Interval, Star-Delta, Flashing, etc.), 24 V AC/DC supply, and 5 A / 250 V AC changeover (CO) contact. The RE17 series (RE17RHMU / RE17RMXMU / RE17RMMW) offers wider functions, larger display, and extended time ranges in a 22.5 mm wide housing — suitable for more complex timing needs.
All models feature a clear LCD/LED display, front rotary switches for function & time range selection, and a test button. They are widely used for pump delay-start, conveyor sequencing, star-delta motor starting, and alarm latching.
Key Features
- Functions: On-Delay (E), Off-Delay (F), Interval (I), Star-Delta (U), Flashing (G), Monostable/One-Shot, Cyclic (Symmetric / Asymmetric) — model dependent (RE11 = 8 functions; RE17 = up to 9–10).
- Time Range: Typically 0.1 s … 100 h (multi-range: 0.1–1 s / 1–10 s / … / 10–100 h).
- Supply Voltage: 24 V AC/DC (RE11RMXMU, RE17RMXMU, RE17RMMW) or 100–240 V AC/DC (RE17RHMU) — check suffix.
- Output Contact: 1 × Changeover (CO / Form C), 5 A @ 250 V AC (resistive).
- Mounting: 35 mm DIN rail (EN 60715).
- Country of Origin: France / Italy (Schneider Global)
