IC200MDD844
Mixed Module, Output 12/24 V DC Pos. Logic 0.5A 16 Points
/ Input 24 V DC Pos/Neg Logic Grouped 16 Points
Thermal Derating
The number of points that can be on at the same time depends on the ambient
temperature, the external voltage, and the orientation of the module and DIN rail.
The following charts display thermal deratings for this module at 24 V and 30 V.
The shaded bands are temperature ranges that represent allowable combinations
of inputs points for the indicated number of outputs points. All combinations of
points are permissible at lower temperatures. The narrow white line within each
range shows maximum temperature when the number of output points equals the
number of input points on at the same time.
