the MOSFET MAX support 10A for DC load, for safety , not use full current.
every 8 output terminal use by one DC point (GREEN TERMINAL), if use output1-output8 all use for 9A load, MAX 9A*8=72A, so the "DC" point will be dangerous, one "DC" point platic green terminal MAX suport 10A. so if only output 9A for output1, output2-output8 not used or use by low current, will be OK.
