I'm in the process of hooking up my relays for the spindle off/on and the coolant off/on. I have reviewed the Gecko wiring schematics but i can't figure out one thing.
The Gecko G540 can control up to 2 relays using pins 5 and/or 6 as well as pin 12 being the GRND. Do I need to provide a separate power supply within that little circuit to activate the relays or does the G540 provide that power through pins 5 or 6 to the relay when the appropriate software command is issued?
Regards
John
