I/O Usage Limits
When using the FC4A-M24BR2 at an ambient tempera-
ture of 55°C in the normal mounting direction, limit the
inputs and outputs, respectively, which turn on simulta-
neously along line (1).
When using at 45°C, all I/Os can be turned on simulta-
neously at input voltage 28.8V DC as indicated with line
(2).
When using the FC4A-M08BR1, all I/Os can be turned on
simultaneously at 55°C, input voltage 28.8V DC.
