Applicable Systems

The A68ADN can be used for the systems indicated below. Please note that
installation of the A68ADN in other systems is not possible.
(1) The following PC CPU modules and remote I/O module can be used with an
A68ADN:
Applicable models
A0J2CPU(P21/R21)
A1NCPU(P21/R21)
A2NCPU(P21/R21)
A2NCPU(P21/R21)-S1
A3NCPU(P21/R21)
A3HCPU(P21/R21)
A3MCPU(P21/R21)
A73CPU(P21/R21)
Applicable remote I/O module
AJ71P25/R25
POINT
The A68ADN cannot be used with the A0J2P25/R25 (remote I/O station)
(2) The A68ADN can be attached to any slot of the base unit. However, the follow-
ing precautions must be taken:
(a) The power supply capacity will be exceeded if the A68ADN is attached to
an extension base unit (A55B and A58B) which contains no power supply.
When attaching the A68ADN to an extension base unit not loaded with a
power supply module, the voltage drop of the power capacity of a power
supply module of a main base unit and the extension cable must be
considered. Keep these factors in mind when selecting a power supply
module and an extension cable.
The User's Manual for each PC CPU module gives details.
(b) In an A3CPU(P21/R21) system, do not use the final slot of the seventh
extension unit to attach the A68ADN. (This restriction does not apply to the
A3NCPU, A3HCPU, A3MCPU, and A3ACPU.)
