Input Module, 24 V DC Pos/Neg Logic 32 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.
There is no derating at 24 V DC. Deratings at 30 V DC are displayed as follows:
