Hello All,
I have a basic application where I am trying to understand the pros/cons of using a surge suppressor diode in parallel with my output solenoids.
I am using an AB compact Logix model (5069-L306ER) with a 24 VDC output model (5069-OB16). The output I am dealing with is a numatics solenoid valve. The solenoid draws very low current (less than 0.5 amps).
Over the years I have noticed that some people use a suppressor diode around the outputs and some do not.
does anyone have any practical recommendations in this regard. My figure below shows solenoids 1 and 2 without the diode and solenoid 3 with the diode.
Thanks
