It does not meet items 4, 5, and 7, but the DT9857E-16-xAO is the nearest product to what you desire. It has 16 simultaneous channels, and each can have IEPE support or be set to a normal AC or DC-coupled single-ended input. It has a +/- 1 and +/- 10-volt input range. The maximum sample rate is 105.4k S/s per channel.
