3.8 Derating outputs
Maximum current carrying capacity based on temperature.
This "derating" must be taken into account for all 2A outputs (IO board and REL board)!
At an ambient temperature of up to 30°C the 2A outputs may be fully loaded.
From an ambient temperature of 30°C to a maximum of 50°C, the 2A outputs may only be
loaded up to a maximum of 1.8A and the total current may not exceed 10A.
