Product Description
Mono-function, multi-voltage
(true) delay on release timer
with 4 selectable time ranges
from 0.1 s up to 10 m for
standard 11-pin circular sock-
ets. Often used in applica-
tions where a cooling fan has
to remain turned on for at cer-
tain period of time after a
motor has been turned off.

S 105
Mode of Operation
When power supply is applied
the relay operates.
When power supply is inter-
rupted, the time period starts
and at the end of the set time
period, the relay releases.
If power supply is reapplied
before the relay releases, the
time is reset and the relay
remains on.
Note:
The S 105 should not be oper-
ated by pulses shorter than
200 ms.
For this purpose the relay
S 103, operated by means of
an external contact function,
should be used.
