Hi everybody,
I would like to control the current inside the different coils. The current change slowly therefore I can model my coils as resistors. The resistances of my coils are comprised between 9-120 ohm. I would like to control the current in proportional way between 0-1A with a signal come from a data acquisition board (NI DaQ USB-6259). The data acquisition board can give me analogical signals (0-5 V) and digital signals. I would like also to switch the current direction.
Can you help me? Can you suggest some components and architecture?
Cheers,
Gioia
