Yes, you do. The induced currents when the field in the coil collapses can cause arcing and welding of relay contacts. You need snubbers on ANY coil that is turned on and off.
I would put snubbers on all coils...cheap insurance.occustoms wrote: ↑Fri Jan 01, 2021 2:42 amYes i understand. i bought extra incase i needed them.martyscncgarage wrote: ↑Wed Dec 30, 2020 12:33 pmWell for 4 axis you only need four relays.
The point being is that you feed the input into the board and you can use whatever you need on the output side.

Question tho If im using a relay on centroid to trigger another relay, that is powering a motor do i still have to have a snubber? i would think not but im not sure.
