Compact solution in cabinet compared to separate timers
TEF5 electronic timers are front-mounted and locked on contactors.
A mechanical indicator allows to show the state of the contactor.
TEF5 electronic timers are supplied by direct wiring 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
1SBC101396F0014 surges in the contactor coil.
Available for a wide control voltage range 24...240 V AC/DC
TEF5-ON or TEF5-OFF allow time-delayed functions up to 100 s in 3 distinct time ranges, inde-
pendently of the control system. The time delay ranges are selected by a switch and the time delay
TEF5-OFF
can be adjusted by means of a rotary switch. The timing function is activated by closing or open-
ing the device on which the timer is mounted. The OFF-delay version operates without additional
control supply.
