soft start time[ms]

Supratim 3 years ago in IQANdesign updated by Jan Gillesen 1 year ago 2

In DOUT there are two functions.

One is Delay on [ms] or Delay off [ms] & the other is Soft Start time [ms] or Soft stop time[ms].

what is the physical effect of Soft start or Stop when we are operating a relay. As per our understanding it will ON or OFF when it reaches the required voltage. So it may be usable for some other load but for any relay or solenoids has it any effect?

Answer

The DOUT Soft Start function is ment to be used when energizing solenoids valves, when you need to create a more soft switching of valve and actuator behind the valve. (Prevent Bang-bang switching) . 
Soft start should NOT be used for energizing solenoids of relays, as a relay needs to switch fast to prevent contacts burning. 

The Peak and Hold function you could use  also for (larger) relays, engergize solenoid with full power, than reduce PWM current to reduce current consumption.
