Time relay,

Do not dispose of this device in the trash along with other waste!
According to the Law on Waste, electro coming from households free of charge and can
give any amount to up to that end point of collec� on, as well as to store the occasion of
the purchase of new equipment (in accordance with the principle of old-for-new, regard-
less of brand). Electro thrown in the trash or abandoned in nature, pose a threat to the
environment and human health.
Purpose
The PO-405 time relay is used to maintain power supply to the
controlled receiver for a specific time after a loss of control volta-
ge, e.g. in bathroom ventilation systems where the fan (switched
on together with the lighting) is maintained for a specific time
after the lighting is switched off.
Functioning
Power supply to the relay is signalled by the illumination of the
green LED. Applying the control voltage to the relay causes its
operation and switching on of the voltage at the controlled re-
ceiver (signalled by lighting of the red LED).
After loss of control voltage the operation of the receiver is
maintained for the maintenance time "t" (potentiometer-ad-
justable). After time "t" the controlled receiver is switched off
automatically.
If the control voltage "S" is applied again before the set time has
elapsed, the relay performs its function from the beginning.
