Are there any disadvantages to using Mesa ethernet boards over using a PCI board?

Ah OK, the 24v is to run the FPGA. A nuissance since I only have a spare 36v regulated supply and the only other 24v supply in the cabinet is AC and unregulated.

Maybe the 5i25+7i76 is a better option afterall.

You still need field pwr with the 7i76. Is the 36v supply for the steppers if so don't take field pwr from that.
what is the 24v AC used for? You could add a rectifier and a cap.

Edit: You could use 12V field power but if you might go with servos later then 24V would be more suitable.

Thanks Clive - I'm sure there'll be plenty more questions when I get to the installation phase.

Anyone have any thoughts on Mesa suppliers in Europe? I found two:

I have ordered from Eusurplus several times 2-3 days to arrive.

For the benefit of others.

I'm inclined to use Eurosurplus. How did you get on with VAT? I notice that they quote without VAT and now we are about to leave the EU I suppose VAT should be collected by DHL. What a chuffing nuissance.

Nothing is going to change in the next 12 months regarding vat
