Wiring Your Analog Channels

Analog input circuits can monitor current and voltage signals and convert them to
serial digital data. The analog output can support either a voltage or a current
function as shown in the following illustration.

You can configure either voltage
or current output operation.
The controller does not provide loop power for analog inputs. Use a power supply
that matches the transmitter specifications as shown below.
