I/O Usage Limits
When using the FC4A-M24BR2 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).
When using at 45°C, all I/Os can be turned on simultaneously
at input voltage 28.8V DC as indicated with line (2).
When using the FC4A-M08BR1, all I/Os can be turned on simul-
taneously at 55°C, input voltage 28.8V DC.
