Guys,
I need your advice regarding connecting a door guard safety relay to the output of a Sauer-Danfoss Hydraulic Valve Amplifier and the proportional valve. I am concerned that switching the output while the valve is energized may cause inductive kick-back and damage the transistor output of the amp. Would adding surge suppression affect the proportional action of the amp? Should the door guard disconnect the 24 vdc input power to the amplfier instead of the output side?
Thanks in advance!
