LEDF True Delay Off Timer Relay

  • True Delay Off
  • Single voltage
  • Single time range
  • SPDT Relay output
  • 17.5mm wide, DIN Rail mount
  • UL Listed

 

The output relay energises as soon as power is applied. When power is removed, the set time delay period commences and the relay will remain energised for this period. After the delay has elapsed, the relay de-energises. Power must be removed and re-applied to restart the function over again.

  • Timing function: True Delay Off
  • Output: SPDT 8A @ 250V (AC1)
  • Dimensions(mm): W:17.5 x H:89 x D:66.5

Supply voltage/time delay options*:
24VAC/DC // 110VAC:
0.5 – 10s (Order Code: 99-2005)
2 – 60s (Order Code: 99-2006)
0.5 – 10m (Order Code: 99-2004)

24VAC/DC // 230VAC:

Typical applications include:

  • Machine shutdown controls
  • Control signal retention circuits
  • Cooling and extraction run-on controls
  • Power-loss alarm interfaces

Key benefits:

  • Maintains a contact state after supply removal — The relay remains energised for the selected delay after the timer supply is removed.
  • Provides a controlled delayed release — After the delay expires, the relay de-energises and changes its contact state.
  • Matches the required shutdown period — The delay is adjustable within the selected time-range version.
  • Interfaces with separately powered controls — The SPDT contact supplies a changeover signal for an external circuit that has its own available power.
