1.3 Cautionary Notes when Selecting a CC-Link Embedded I/O Adapter
1 - 3
The following explains the cautionary notes and specifications that apply when
selecting a CC-Link embedded I/O adapter for use in the CC-Link system:
(1) This is a embedded I/O adapter designed specifically for the CC-Link system.
Do not connect the adapter to other data-link systems, such as the
MELSECNET/MINI.
(2) 32 points are assigned per station for a CC-Link embedded I/O adapter.
The second-half 16 points of a 16-point CC-Link embedded I/O adapter are empty
but are not usable.
(3) For the maximum switching frequency when driving a load in the CC-Link
embedded output adapter, set to one second or more each for ON and OFF.
(4) When using a counter, a timer or the like that uses a DC/DC converter as the load
for a CC-Link embedded transistor output adapter having a maximum load current
of 0.1A, a rush current flows when the adapter is turned on and at fixed intervals
during operation. For this reason, malfunctions may occur if the average current
is set. When the above load is used, connect resistance or inductance in parallel
to the load, or use an output adapter having a large maximum load current in
order to minimize the effects of the rush current.

(5) When using the AJ65MBTL1N-16D, AJ65MBTL1N-16DT or AJ65MBTL1N-32D
CC-Link embedded I/O adapter, the maximum number of simultaneous input
points listed in the specifications will change, depending on the ambient
temperature.
The maximum number of simultaneous input points is shown in the diagram
