VL-TR-RT8(S)-Y — Star-Delta Motor Starting Time Relay
The star-delta time relay is designed for motor star-delta starting control, helping reduce starting current and ensure stable motor operation during startup.
It supports a wide working voltage range, with Y1 available for AC/DC 24–240V and Y2 available for AC/DC 100–380V. The relay features real-time LED status indication, optional digital display or rotary types, and a compact 18mm modular design for easy installation on standard 35mm DIN rails.
Key Features
- Dedicated star-delta (Y-Δ) motor starting control to reduce inrush current
- Y1 loop AC/DC 24–240V, Y2 loop AC/DC 100–380V (or fixed 220V/380V variants)
- Independent transition-time (t1) and delta-time (t2) settings
- Rotary or digital-display setting with real-time LED indication
- Compact 18mm width, standard 35mm DIN rail installation
