3.1 Replace A/QnA (Large Type) Series with Q Series
3.1.2 Utilize existing I/O modules and extension base unit with Q Series CPU
(Use QA conversion adapter)
Solution and Benefit
The QA conversion adapter module enables the existing extension base, including the mounted I/O
modules, to connect to a Q Series main base unit. This can shorten the installation and wiring
modification times.
The following is an example of reusing existing A (Large Type) Series modules with a Q Series CPU using the
QA conversion adapter module.
● Instructions
(1) Replace the A (Large Type) Series CPU with the Q Series CPU (Q03UDCPU) and mount it on the Q Series
main base unit (Q3 B).
(2) To reutilize I/O modules mounted on the existing A (Large Type) Series main base unit, mount them on the
QA6 B extension base unit.
(3) Mount the "QA6ADP" adapter on the connector of each existing extension base unit to allow the use
of existing modules.
(4) Connect the base units with the Q Series extension cable (QC B).
