Compact solution in cabinet compared to separate timers

TEF4 electronic timers are front-mounted and locked on AF contactors or NF contactor relays.
A mechanical indicator allows to show the state of the contactor.


Safe and cost-reduced wiring

TEF4 electronic timers are supplied by a direct plug-in parallel connection to the coil terminals A1 - A2 of
the contactor or contactor relay. A varistor is integrated on the timer to offer a built-in protection against
surges in the contactor coil.


Available for a wide control voltage range 24...240 V AC/DC

TEF4-ON or TEF4-OFF allow time-delayed functions up to 100 s in 3 distinct time ranges, independently
of the control system. The time delay ranges are selected by a switch and the time delay can be adjusted
by means of a rotary switch. The timing function is activated by closing or opening the device on which the
timer is mounted. The OFF-delay version operates without additional control supply.

 

Time delay range (selectable via dip switch)
0.1...1 s
1...10 s
10...100 s

 

Note: Rated control circuit voltage Uc 24...240 V 50/60 Hz or DC.
