0.0 ... 1250.0 seconds The switching on time is limited to 20 % of the cycle time
The cycle times are to be taken into consideration when actuating solenoid valves (PWM = pulse width
modulation).

Fig. 13: Solenoid valves
The switching times of the relay (solenoid valve) depend on the
actuating variable and the "min. time" (smallest permissible
switching time of the connected device). The actuating variable
determines the ratio t
on
/cycle and thus also the switching times.
The "min. time" affects the switching times in two situations:

The DULCOMARIN
®
3 does not switch on for a certain number of
cycles until the sum of the theoretical switching times exceeds the
"min. time". Then the DULCOMARIN ® 3 switches for the duration
of this total time.
