Subject: 24V Pull Down
Greetings,

I have a Konnect board and am running a linear servo motor off of a KFlop. Problem is all of the IO for the linear servo is 24V activated when pulled to ground. The Konnect wants to source 24V not sink. Am I stuck with adding relays driven from the Konnect? Would it be a bad idea to use one of the KFlop pins to pull the voltage down (the linear servo has very low current, and it works when I connect directly to the 5V Ground)?

Control panel is getting packed.. hoping to find a way to do this without adding 4 more relays. Any ideas?


Thanks,


Scott

Scott,

the Konnect outputs act like switches. They don't source or sink anything other than what you connect to them. Only thing you have to make sure is you get the + and - the right way around for whatever you're connecting.
