The LE4S series digital timers feature LCD Backlight display with a compact, space-saving design. The timers also feature various output operation modes as well as configurable time setting range and one-shot output time for diverse applications. Users can configure set value and time range independently in the flicker, flicker I, ON-OFF delay, and ON-OFF delay I modes.

The LE4S digital LCD timer from Autonics is a digital timer with display LCD (with backlight), 10 modes, and multiple time ranges.

The LE4S digital LCD timer from Autonics comes with the following upgraded features:

  • Digital backlight LCD timer. DIN size W48 x H48mm.
  • Mounting space saving with a compact design:
    Downsized by approx. 22% in depth compared to existing models.
    (Length of the panel on the backside is 56mm).
  • Available to set each value and time range separately when choosing flicker (FK, FK I) or ON/OFF delay (ON-OFF D, ON-OFF D I) outside modes.
  • Adds flicker 1 mode (LE4SA).
  • Selectable 1 shot output timer (0.01-99.99sec.).
    (Existing model fixed 0.5 sec.)
  • Configurable time range (added 9.999 sec.). Settable by 0.001 sec. unit.
  • Selectable min. input time 1ms or 20ms (LE4S).
  • Improved return time 100ms.
