relay question

[homebuilder64]

the diagram here shows a relay contact. but i was told that this item is a capacitor 0.1UF 600v and the 100r stands for 100 ohms resistor the diode is self explained i would like some leads where to get an item that might have both the capacitor and resistor in one unit or do i have to use a bred board to insert these item to make the schemactic work correctly

thanks for the help i notice there looks like a switch there as well is the capacitor the switch part as well or do i need to add a switch to this electrical plan? not quite sure about that if i need to add switch or is capacitor is the switch when power is introduced in to the system ?

I think the ''switch'' that you are looking at are the relay contacts. What do you plan on using the relay for?

i am building a 4 axis cnc machine i am using 4-Axis CNC Mach3 USB Motion Controller Card Interface Breakout Board

and the corner that's exploded is a little confusing to me i understand the rest if the diagram but i don't want to hook it up and destroy all my electrical components

[Jim Dawson]

I'm a bit confused here, O1, O2, O3, and O4 are just outputs, could be used for anything. The relay is not needed at all unless you have a specific use for it.

it shows spindle start in manual unless i am reading it wrong there's power being delivered to 02 if you follow the 24 positive line from power supply

[Jim Dawson]

O1 is the spindle enable output, the return path is COM. Has nothing to do with O2. O2 is shown powering an auxiliary relay the output of which is connected to nothing.

OK thanks for the clarification
