2.2 Applicable Systems
( I ) The AlSD71 is only applicable to an AlSCPU module.
(2)
The number of A l S D 7 I used with an AISCPU module must be within the
range of the number of I/O points of the AISCPU.
(3) The AlSD71 can be installed in
any
two-slot area of a base unit, but the
following must always be considered:
(a)
If
possible, avoid installing the AlSD71 in an extension base unit
(AlS52B, A1S55BI AlS58B)
not
equipped with a power supply
module, since the power supply capacity may be insufficient.
(b) If it is necessary to install the AlSD71 in an extension base unit
which does not have a power supply mpdule, select a power supply
module, main and extension base units, and extension cables taking
into consideration (a) the power supply capacity
of the main base
unit, and (b) the voltage drop across the main and extension base
units and extension cables.
(See the AISCPU User's Manual for details.)
