Solution
If your NI device has channel to channel isolation, it is possible to stack channels to achieve higher current and voltage outputs.

By stacking channels in series, voltage output can be multiplied. Each channel added to a stack will multiply the per-channel maximum further. In the photo above, the per channel limit is ±16 V. Each channel added to the series connection will add ±16 V to your total output.

By stacking channels in parallel, current output can be compounded. In the photo above, the per channel limit is ±20 mA. Each channel added to the parallel connection will add ±20 mA to your total output.
