the maximum logic and field power for all modules installed on a baseplate.
(Field power is the percentage of field circuit power that is dissipated within
the controller.) If spares are present, add the same amount of logic power as
the primary modules.
For more information about cooling, contact the Triconex Customer Response
Center.
Calculating Logic Power
Note
Information in this section is based on a fault condition in which only one
of the redundant power sources is operational. Under normal operating conditions,
both power sources share the load.
To determine the maximum logic power supply needed, use the following table to
sum the maximum logic power for all modules, including hot spares, to be installed
on a baseplate.
