While the analog outputs may each be remapped at the final
configuration popup, they may also be remapped using the Analog
I/O Mapping option on the Analog Inputs Setup menus. Selecting
this option invokes the Analog I/O Mapping configuration popup as
shown in Figure 53. Each analog output may be mapped to one of the
analog input resources, including the two dedicated thermistor inputs.
Selecting a different analog input channel for any given analog output
cancels the existing mapping for that output. However, multiple analog
outputs may each be mapped to the same analog input, which may
each have their own specific setpoints associated for their particular
application.
For example, two analog outputs may use the primary differential
pressure input on AI-1 to satisfy two different control objectives. AO-1
may control the exhaust valve to maintain a target differential pressure
whenever the pressure is within a specific range. Simultaneously,
AO-2 may control the supply valve to maintain a specific volumetric
offset between the supply and the exhaust.
The next section discusses the options available on the Digital Inputs
Setup menu and the configuration of the secondary digital inputs on
the FMS-1650.

resources may be

is used by each analog
output.
