In general, each output circuit is rated for 1.5 Amps from 0 to
40º C, derated linearly to 1.0 Amps at 60º C. All eight outputs
can simultaneously operate at these levels, producing a total
module current rating (total of all eight output circuits) of 12
Amps from 0 to 40º C, derated linearly to 8 Amps at 60º C.
Applications that require higher output current ratings are
allowable, but only if the total module current is reduced. You
may operate output circuits as high as 2.0 Amps from 0 to 40º
C, derated to 1.5 Amps at 60º C if you reduce the current on
the other remaining outputs. For example the combination of
output load ratings shown in Table 2 are allowable.

Output Load Types
The isolated Guarded output module is ideally suited for
controlling safety critical loads including motor starters as
large as NEMA Size 5. Their are some applications that may
not be suitable for using the isolated Guarded output module
which are described below. For these applications, other
output module types available for the system should be
considered. Refer to the specific Product Descriptions of these
modules for their application and specifications.
