LEYD/A Star/Delta Start Timer

  • Star/Delta Start
  • Selectable Dwell times (7)
  • Multi-voltage (12 – 230VAC/DC)
  • Multi-time range (0.1s – 100h)
  • SPDT Relay output
  • 17.5mm wide, DIN Rail mount
  • UL Listed

When power is applied, the output relay remains de-energised for the set time delay period. After the delay has elapsed, the contacts “break” for the set Dwell time, then changeover to the energised state. Power must be removed and re-applied to restart the function over again.

  • Timing function: Star/Delta Start

  • Time delay: 0.1s – 100h
  • Dwell time:  40, 60, 80, 100, 120, 140, 160ms
  • Output: SPDT 6A @ 250V (AC1)
  • Dimensions(mm): W:17.5 x H:89 x D:66.5
  • Product standard(s): IEC 61812

Typical applications include:

  • Industrial pump starters
  • Air compressor starters
  • Industrial fan and blower starters
  • Motor control centres

Key benefits:

  • Coordinates the star-to-delta transition — The output follows an initial timing period, a selected contact break dwell and then the energised changeover state.
  • Allows time between contactor commands — Seven selectable dwell settings create a break period before the output changes to its energised state.
  • Matches the initial starting period — The main time range and fine adjustment allow the star period to be selected for the starter requirement.
  • Fits different starter control supplies — The multi-voltage AC/DC input supports a range of documented control-supply arrangements.
