Analog outputs (module ID 2)
The Analog Output (AO) module provides four outputs at 0 mA to 20 mA (configurable for 4 mA to
20 mA or any span between 0 mA to 20 mA). When not used for an analog output, an output channel may
be used to power a transmitter with 24 Vdc power. The controller will support up to 4 AO modules, for a
total of 16 outputs. Figure 15 shows the terminal connections for the AO module. See Specifications
section for details on all I/O module specifications.
