LEDO/2 Delay On Operate Timer Relay

  • Delay On Operate
  • Multi-voltage (12 – 230VAC/DC)
  • Multi-time range (0.1s – 100h)
  • DPDT 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 relay energises. Power must be removed and re-applied to restart the function over again.

  • Timing function: Delay On Operate
  • Supply voltage:  12 – 230VAC/DC +/-15% (-10% if AC) (Order Code: 99-2104)
  • Time delay: 0.1s – 100h
  • Output: 2 x SPDT 8A @ 250V (AC1)
  • Dimensions(mm): W:17.5 x H:89 x D:66.5
  • Product standard(s): IEC 61812

Typical applications include:

  • Pump control panels
  • Conveyor systems
  • Ventilation plant controls
  • Industrial machine start circuits

Key benefits:

  • Introduces a defined start delay — The relay remains de-energised for the selected period after power is applied before energising.
  • Coordinates two delayed responses — Both changeover poles energise after the same delay, allowing separate control and signalling circuits to follow one sequence.
  • Adapts to different start sequences — Selectable ranges and fine adjustment allow the delay to be set to suit the equipment sequence.
  • Works across AC and DC control supplies — The multi-voltage supply range allows the timer to be used on different supported control voltages.
