Voltage (DAC) output
The multifunction module has two analog outputs capable of outputting
calibrated voltages between ±12 volts with 16 bits of resolution. Each DAC
(Digital-to-Analog Converter) channel can be used as a programmable voltage
source for analog input control of other devices. A simplified diagram is shown
below.
– You can set the output voltage to any value between +12 VDC and -12 VDC, in
1 mV steps. Each DAC is earth referenced; it cannot float.
– Each DAC channel is capable of supplying 10 mA maximum current.

You must limit the output current to 40 mA total for all three slots (six DAC
channels).
