Counter/Timer : LE4S Series
DIN W48×H48mm Digital backlight LCD Timer
Upgraded back light type digital LCD timers LE4S/LE4SA are downsized by approx. 22% saves mounting space and adopted the new design nameplate. In addition, it is 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) output mode. New LE4S/LE4SA's upgraded powerful functions of wide variety would fully satisfy customers’ needs.
Main features
* Mounting space saving with compact design
: downsized by approx. 22% in depth compared to existing models (Length of panel on the back side 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) output mode (existing model: setting value only)
* Add Flicker 1 mode (LE4SA)
* Set One-shot output time (0.01~99.99sec) (existing model : Fixed 0.5 sec)
* Time range is configurable (time setting range to 9.999sec) : Able to set to 0.001sec (existing model : 0.01sec)
* Choose Min. input signal : 1ms or 20ms (existing model: Fixed 20ms) (LE4S)
* Improved return time: 100ms (existing model : 300ms, 500ms)
* Back light ON/OFF function
* Providing more easy function setting modes
* Wide time range
* Lock setting function for saving setting value.
* Function setting with soft touch
* High visibility display with back light
* Wide range of power supply: 24-240VAC 50/60Hz, 24-240VDC
