IC200ALG320
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.
