Module Limitations
Input Voltage Derating
You must derate the input voltage that is applied to each input channel, based on
operating ambient temperature, to keep module power dissipation within an
acceptable level.
Sensor-Power Derating
You must derate the allowable current from each channel sensor-power port
based on operating ambient temperature to keep module power dissipation to an
acceptable level.
