Current/Voltage Output
Controllers with output codes “AO,” “AA,” “AR”
and “AT” give you the option of 4-20mA or 1-5 Vdc
output. When shipped from the factory, these
control outputs are configured for 4-20mA output.
For 1-5 Vdc output, you must access the internal
output board and move the jumper(s) to the 1-5
Vdc position, as shown in Figure 2.16 on the
following page.
