IC200MDD848
Mixed Module, Output 120VAC 0.5A per Pt Isolated 8 Points /
Input 120VAC Grouped 8 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 120VAC and 132VAC. 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.
