IC200MDD842
Mixed Module, Output 24VDC Pos. Logic 0.5A Grouped w/ESCP 16 Points
/ Input 24VDC 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 charts that follow
show thermal deratings for this module at 24V and 30V. 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 that are on at the same time.
