Output Module, 5/12/24VDC Negative Logic 0.5 Amp, 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.
The charts below show thermal deratings for the module at 24VDC and 30VDC with
the maximum output current per point.
