I have a coil with 1 ohm resistance that requires about 600 mA current input to give the magnetic field I want. I already use a current supply for that, but I want to remove this current supply and use a DAQ device instead. I can control the voltage on the analog output channels of this device at -10 to +10 V, but the max current that this device can resist is only 80 mA. I don't want to blow up the device by exceeding the current. Does anyone have any idea how can I feed the required current on the coil by tuning the voltage on the AO channel of the device?
