Mixed Module, Output 120 V AC 0.5A per Pt Isolated 8 Points /
Input 120 V AC 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 following charts display thermal deratings for this module at 120 V AC and
132 V AC. 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.
