The legacy National Instruments AT-AO-10 is a 12-bit analog output board for ISA computers. Please consider instead our newer and higher performance
NI 672x devices (for PCI and PXI) The NI AT-AO-10 has 10 identical output channels, each of which has voltage output and can sink 4 to 20 mA current when connected to an external source. The voltage output of each channel is either bipolar or unipolar and is derived from the onboard reference or an external reference. A built-in 8-bit digital I/O port provides additional control capability.
