MN1949WEN Input / Output 3-5
3.1.3 Analog outputs
 Four independent bipolar analog outputs.
 Output range: ±10 V (±0.1%).

Resolution: 16-bit.

Output current: 10 mA maximum.
 Update frequency: 1 kHz.
All of the outputs may be used as general purpose analog outputs - see the
DAC
keyword in
the Mint help file. The analog outputs may be used to drive loads of 1 k
Ω
or greater. Shielded
twisted pair cable should be used. The shield connection should be made at one end only.
Figure 3-7: AOUT8/16 analog output circuit
When the MotiFlex e 100 is connected to Mint WorkBench, the analog output value
(expressed as a percentage) can be viewed using the Spy window's Monitor tab. The
DAC
command can be used in the command window to set the value of an analog output as a
percentage of full scale. For example, assuming the card is mounted in slot 1, the command
DAC(8) = 50
will set analog output 8 to +50% (approxi5 V). See the Mint help file
for details.
3.1.4 Power consumption
The maximum overall power consumption of the Analog I/O option card is 2.8 W. See the
main MotiFlex
e 100 installation manual (MN1943WEN) for further details about the option
slots’ power supply and derating information.
