The analog outputs (AO) provide a 4 to 20 mA current source output for
powering analog loop devices. Analog outputs are analog signals the
FB107 generates to regulate equipment, such as control valves or any
device requiring analog control. The AO includes the power supply
connections. The analog outputs use a 12-bit D/A converter with default
A/D values of 0 and 3250 (0 to 100% EU values).
Select AO as the I/O Type for the selectable analog
Note:
output/discrete output when you configure it for use as an analog
output. Refer to Figure 4-5.

Wiring the Analog Outputs

The terminals provided on the CPU module for connecting AO wiring
are:
AO+ Positive
AO Common
You can induce ground loops by tying commons from various modules
together.
Figure 4-11 shows wiring for the analog output.
