Input Usage Limits
When using the FC4A-N16B1 at 55°C in the normal mounting direction, limit
the inputs which turn on simultaneously along line (1). At 45°C, all inputs
can be turned on simultaneously at 28.8V DC as indicated with line (2).
When using the FC4A-N16B3 or -N32B3 at 55°C, limit the inputs which turn
on simultaneously on each connector along line (3). At 30°C, all inputs can
be turned on simultaneously at 28.8V DC as indicated with line (4).
When using the FC4A-N08B1, all inputs can be turned on simultaneously at
55°C, input voltage 28.8V DC.
