Examples
NOTE: the use case is for reference only to understand the working principle of the relay. The actual application should be wired
according to the actual needs.
CASE1:
The working mode is set to 07 and accessed through the
sensor (PNP). When the sensor senses the signal, the relay
acts (15-18 is closed) and the ventilation fan works. When the
sensor loses the signal, the relay disconnects after a delay t
(15-18 is disconnected) and the ventilation fan stops working.

CASE 3:
When the working mode is set to 02, the time relay is powered
on (15-18 is closed), the contactor is closed, the water pump
starts to work, the delay t reaches, the relay is disconnected
(15-18 is disconnected), the contactor is disconnected, and the
water pump stops working.

Disposal of Electrical Waste
All electrical waste should be
disposed of in compliance with
current WEEE regulations.
CASE 2:
The working mode is set to 03, the ventilation fan is turned on
for 10 hours and turned off for 1 hour, and the ventilation fan
is cycled on and off.
