When using at 45°C, all I/Os can be
turned on simultaneously at input volt-
age 28.8V DC as indicated with line
(2).
When using the FC4A-C10R2/C, all
I/Os can be turned on simultaneously
at 55°C, input voltage 28.8V DC.
For other possible mounting direc-
tions, see page 3-12.

I/O Usage Limits
When using the FC4A-C16R2/C or FC4A-C24R2/C at an ambient temperature
of 55°C in the normal mounting direction, limit the inputs and outputs,
respectively, which turn on simultaneously along line (1).
