I have here a 4axis dnc controller came from salvage industrial machine, according to the manual it need 10-24v 5mA for the Inputs terminal, i try to hook it up with a 1A 24v power supply because i cant find any power supply with 5mA, and it doesnt work and the power supply shut itself off. Do i really need a 5mA power supply to make it work? Or do i need a transducer for this to work?
