Analog Output Module, 13 Bit Current, 12 Channels
Thermal Derating
The number of channels that can be active at the same time depends on the ambient
temperature, the external voltage, and the orientation of the module and DIN rail. There is
no thermal derating for this module at 24V. The chart below shows thermal deratings for
this module, on certain carriers, at 30VDC with the module and DIN rail in the
orientations shown. There is no derating at 30V in other orientation and carrier
combinations.
To meet thermal derating requirements, inactive channels should be distributed evenly
across the total number of output. For example, the "A" orientation graph below reflects
the derating with channels 1, 5, and 9 inactive.
