Time functions (relay output) can be started or interrupted by the three inputs i.e., ON, OFF or
TOGGLE (pins 3, 4 and 5).
The relay becomes active if the time function is triggered, and the relay contact is interrupted

To avoid simultaneous operation of both inputs, pin 3 (ON) and pin 4 (OFF), use of two-way con-
tacts with a centre-off position with spring returns (also known as rocker-actuated switch) is
recommended (see
Pressing the push-button switch (pin 3-ON) leads to the activation of the relay after the
debounce time, t
being de-energized. If the relay is not de-energized by the push-button switch, it becomes dis-
abled after the delay time, t
Combined operation, TOGGLE and ON/OFF is not possible because both inputs are connected
to the same debounce stage. Debouncing functions on both edges i.e., whenever S

If pin 3 (input ON) is continuously closed, the delay time, t
