Can someone help me understand this relay circuit? I'm have trouble figuring out how to wire it correctly. Thanks.

Got it. That makes much more sense now. ThanksThe capacitor and resistor combo is called a Snubber, in the diagram, it goes across the relay N.O. contacts.
What is it switching?
Max.
That relay is used to switch on the spindle of the cnc.Is this an MB2 system?
If so, it just looks as though this is a typical connection for the outputs, and appears this is just an example of a typical output usage and thus if not switching an inductive load with the relay, the R/C snubber is not really required.
Also in the case of the MB2, I believe they are opto coupler outputs and in some cases may not require a relay, i.e. DIR input to a VFD etc.

Thanks again! I'll try it with out the snubber and go from there.Then you don't need the snubber circuit, in fact you may not need the relay !
