Installation and connection of the digital-timer must only take place in the powered-down condition.
Only a specialist familiar with the applicable safety provisions and regulations must perform this work.

The rated voltage of the load determines the operating voltage of the digital timer (e.g.: 12 volt coil voltage
of the relay = 12 V operating voltage of the timer). The operating voltage is only connected after the desired
switching time was set at the coding switch. Otherwise, the timer will start at once!
For assembly on the DIN 35mm rail, the snap-base element (type UMK-FE) order no.: 74 32 77
and 2 side elements (UMK-SE 11,25-1) order no.: 74 10 63 are required.

Selected
time
Digitally adjustable short- and long-term timer with switching
times from four seconds to 34 hours.
If the button is pushed before the end of the selected period,
the total time increases by the set time (retriggerable).
- Wide operating voltage range
- Low current consumption
- Pushbutton debouncing
- High switching current
- Suitable for assembly on top-hat rail
