LESW/2 Switch Initiated Delay Off Timer Relay

  • Delay Off (Switch Initiated)
  • Re-triggerable function
  • Additional external loads can also be controlled by same trigger contact
  • 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 in the de-energised state. When the external contact closes (i.e. switch), the relay energises and remains in this state. As soon as the contact opens, the set time delay period begins and the relay continues to remain energised for this period. After the delay has elapsed, the relay de-energises.

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

Typical applications include:

  • Industrial dust extraction
  • Machine cooling systems
  • Building ventilation systems
  • Lighting and ventilation controls

Key benefits:

  • Keeps equipment running after demand ends — The relay remains energised for the set period after the external trigger contact opens.
  • Extends run-on when demand returns — If the contact closes during timing, the delay stops and starts again from the beginning when the contact next opens.
  • Coordinates control and indication — Two changeover poles apply the same timed state to separate control or signalling circuits.
  • Shares one trigger with another load — The trigger input supports suitable external loading, allowing the same contact to command the timer and an additional load.
