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 30 V DC
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 as follows reflects the derating with channels 1, 5, and 9 inactive.
