Memory modules & IC’s
All AnU, AnA, AnN and QnA CPU’s require the installation
of a memory module or chip before they can be
operational. The memory modules and IC’s available for
use are shown in the table below. Maximum memory and
CPU modules to which they are applicable are indicated.

Power supply modules
Each A Series system requires at least one power supply
module inserted into the CPU base. Additional power
supplies are necessary if A65B or A68B extension base
units are used in the system configuration. The power
supply requires an external power source of either
100/120VAC or 200/240VAC for A61P, A62P, A61PEU,
A62PEU & A65P, 24VDC for A63P.

LVD compliant modules
From the 1st January 1997 the Low Voltage Directive (LVD)
became mandatory within the EU. This directive is mainly
concerned with the safety of electrical equipment operating
above specified voltage levels. A61PEU, A62PEU and A63P
have been newly developed to comply with relevant
European safety standards EN61010-1 and EN61131-2
(applicable safety clauses only).
Model number Input voltage Rated output
