Thanks again I am scratching my head as to why I didn’t see it how ever the problem is solved I have ordered a 24 volt AC relay and a Block transformer from RS Components the transformer is coming from overseas I also have to import the KB DC drive as the 230 volt DC model is not stocked in NZ. When completed I will report how successful the modification is it will still be cheaper than purchasing a new power feeder and I will be able to get parts.

I have this link to article it is very similar to what I intend to do, if you take a look at the circuit diagram or page 10 I wonder how he operates the 24 volt DC relay with 110 volt AC transformer.

Something else I was trying to size AC transformers I hadn’t twiged the relay coils were DC thanks for jolting my memory.

Thank you all so much for all the help, my workings were on the right track you all have sorted it for me I am sorry I didn’t say that the 24 volt coil is DC and is going to be PCB mount I can buy a 240volt AC 24 volt DC regulated PCB mount transformer up to 5 watts from RS components or incorporate a rectifier in the circuit board that’s the cheapest option only problem is not to much space to work with.

I’m stumped perhaps it is age related,l am modifying a Seig sx3 dc power feed and can’t work out the size of of the 240v 24v transformer to operate a 24 v 550 mW coil on a relay. Ask me to make or fix something no problem just cant get my head around this.
