5.12 Accessories for AC500-eCo
This section only describes accessories that are frequently used for system assembly, connec-
tion and construction.
5.12.1
Mounting and demounting the option boards
5.12.1.1
Optimized mounting of the option boards
The AC500-eCo processor modules have up to 3 slots for option boards.
The best thermal circulation is given on slot 3 (bottom slot), followed by slot 2 (middle slot) and
then slot 1 (top slot).
The best mounting position of the option board depends on its power dissipation.
Rules for optimized mounting of the option boards
–
The greater the power dissipation of the option board, the lower the
mounting position should be selected.
–
The TA5126-2AO-UI option board has the highest power dissipation
and must always be mounted at the lowest option board slot.
The optimized mounting position can be easily determined with the help of this
table.

If the option boards to be mounted are in the same power dissipation level, then
the slots can be freely selected.
