CPU base units
One CPU base unit is required for each AnU, AnA, AnN or
QnA system. Each allows for one power supply module,
one CPU module, and a maximum of either 2, 5 or 8 single
slot size I/O modules. At either end of the base unit there
is an expansion port for the connection of extension bases.
■
Extension base units
There are two different types of extension base units. One
which allows for a power supply module; the other, which
does not. Selection of which type should be used depends
on the total 5 VDC current demand made on the power
supply in the CPU base unit. If this total demand is lower
than the output of the one power supply, then an
additional power supply is not required and the more
economical extension base unit can be used. There are two
extension ports at either end of the unit and connection to
other base units is made via extension cables.
■
Extension cables
These extension cables are used to connect two base units
together. There are three different lengths of cable
available: as shown below.
