Our current design includes freewheeling diodes on speed critical DC pneumatic solenoids. The purpose is supposed to be to speed up the response. We generally use Contrllogix 24VDC output cards to fire the solenoids.
I am of the opinion that the diodes will have no effect on the solenoid energizing time, and actually slow down the shut off. Does anyone have any practical experience where diodes have been used to successfully improved DC solenoid speed?
Thanks
