So, truth be told, I don’t know how much current the closed 9v circuit would draw.
I’m assuming it’s not much, as it’s likely just triggering another relay inside the device (I can probably check this).
EDIT: There is no electrical schematic, but they do show a 24vdc solenoid in the parts list. I could pop the cover and see if that’s where the foot pedal goes, but there isn’t another likely candidate for the switch to trigger.
EDIT #2: The electrical schematic is under the hood (bless them) and calls for a mechanical relay.
If I can figure out how to post a picture, I’ll include that.
From your perspective, speed isn’t an issue: 500ms should be plenty fast enough. I don’t think I need to worry about timing, but could actually adjust your software to compensate, if that turned out to be necessary.
