Ac vs dc coil on contactors

Post by Jhuff »

Looking at schematics does it make any difference if I use dc coil contactors to drive the servos on a mill. I will use 24 volt dc power supply. Does the oak board care to switch. Dc vs ac?

Make sure to use the proper snubbers on the coils. Diodes are preferred over Quencharcs for DC coils. Oak outputs are rated up to 5A at 30VDC.
