Thanks for the reply, I have thought about it before and came to conclusion that it can be used that way after posting these questions and reply from NI apps engineer who replied that
This module can in fact support this as long as you are switching all 16
channels simultaneously. It should even work driving 10A split amongst
10 channels (max 1A per channel), but it is probably best to lower the
current per channel a bit to ensure you remain within spec.

The NI 9477 module can sink up to 625 mA/ch of continuous current on all
channels, or up to 1 A/ch of current on up to 20 channels. In other
words, the per-channel limit is 1 A and the total current limit for all
32-channels is 20 A. You can also connect multiple digital output
channels in parallel and use simultaneous switching in your LabVIEW FPGA
application to send up to 20 A of current and 60 VDC to a single
actuator, motor or solenoid. That’s 1200 watts of power, or 1.6
horsepower.
I have designed an array of 32 fuses of 1 amp each in front of the module pins, and have a 32 dip switch to allow the required number of channels to be connected together to the motor connection to split the current as per the above devzone article parallel scheme.
Please let me know if you think this wont work or have a better scheme, i still dont want to ruin my device, I am following what was suggested to me.
Thanks,
