Just to clarify my board diagram is this attachedHi many thanks for the reply.
Machine is a Cemont maximig 180.
Board that I bought is exactly the one that Aftronica mentioned.
I am struggling because power supply is a single power supply with ac24v output, struggled on this wiring and got even more confused when I read "u can use single supply ,wath need to do is cut out relay contacts from pcb regards".
More confuse even because I am a beginner in electronics when I saw on aftronica two different wiring diagrams.
Specifically this attached that maid me think what to do with pin 1 and 2 are they input ou output?
Any help is welcome
Many thanks for the hospitality
Regards
