Electronic timers - with spring terminals

Description
TEF4S frontal electronic timers are used for realizing timing function and are available in ON-delay and
OFF-delay versions.
1SBC101394F0014 TEF4S electronic timers are front-mounted and locked on AF..S contactors or NF..S contactor relays.
Compact solution in cabinet compared to separate timers
A mechanical indicator allows to show the state of the contactor.
Safe and cost-reduced wiring
TEF4S-ON TEF4S 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
TEF4S-ON or TEF4S-OFF allow time-delayed functions up to 100 s in 3 distinct time ranges, indepen-
dently 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.
