I/O Usage Limits
When using the FC4A-D20K3/S3 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 the FC4A-D40K3/S3, limit the inputs and outputs, respectively,
which turn on simultaneously on each connector along line (2).

When using at 40°C, all I/Os can
be turned on simultaneously at
26.4V DC as indicated with line (3).
When using the FC4A-D20RK1/
RS1, all I/Os can be turned on
simultaneously at 55°C, input volt-
age 26.4V DC.
