Analog Output Module, 12 Bit Current, 4 Channels
Thermal Derating
The minimum recommended load resistance per channel depends on the
ambient temperature, the external voltage, and the orientation of the module
and DIN rail. The thermal derating is not affected by the type of carrier on which
the module is installed.
The total load requirement includes the impedance of the transducer being
driven. At higher ambient temperatures, it may be necessary to add resistance
in series with the load to reach the minimum load requirement.
