1sbc100004V0014 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-ON
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
1SBC100012V0014 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
TEF4-OFF additional control supply.
