2.2 Replace AnS/QnAS (Small Type) Series with Q Series
(2) Compatibility of AnS size version Q Series large type base unit with the upgrade tool
The following table shows the compatibility of AnS size version Q Series large type base unit with the upgrade
tool manufactured by Mitsubishi Electric Engineering Co., Ltd. when replacing existing A (Small Type) Series
modules with Q Series modules.
Slot width of base unit
Power supply module
• I/O module
• Intelligent function
For terminal block type 16-point I/O module (1-slot type)
For terminal block type 16-point I/O module (2-slot type)
For high-speed counter module
For analog module (1-slot type)
Connection of QA/QA1S extension base unit*
*1: AnS size version Q Series large type base units, Q Series base units (standard products) and Q Series
large base units can be used together.
*2: Mount a Q Series base unit (standard product) on the base adapter manufactured by Mitsubishi Electric
Engineering Co., Ltd.
*3: Q00UJCPU is not compatible.
*4: The following modules cannot be used.
• A module whose height is more than 98 mm.
• A module with a bracket on top.
• A module with a protrusion, such as a connector, on
• A module onto which Q7BAT-SET is mounted.
Q66AD-DG, Q66DA-G, Q68AD-G, Q68RD3-G, Q68TD-G-H02, Q64AD2DA, QD75M1, QD75MH1,
QD75M2, QD75MH2, QD75M4, QD75MH4, or QJ71WS96 with Q7BAT-SET mounted.
*5: Since the adapters are mounted on Q Series modules, the specifications and functions are same as those
of the Q Series modules. (Please check the transition handbook, since the specifications and functions
are different from those of A (Small type) Series module)
*6: The AnS size version Q Series large type blank cover (QG69LS) must be mounted.
*7: Only High Performance Model QCPUs can be connected to the QA/QA1S extension base unit.
This cannot be used with the MELSECNET/H remote I/O station, etc.
*8: If the size of the copper wire connected to the terminal block is larger than 1.25 mm
mount the conversion adapter.
In this case, secure wiring space by leaving empty slots in between modules. For example, mount modules
on slot No. 0, 2, 4, 6, 8, and leave slot No. 1, 3, 5, 7 empty. Mount a blank cover QG60 on the empty slots.
If there are not enough slots, consider using the AnS size version Q Series large type base unit.
*9: Applies when using replacing the existing A (Small Type) module with the two Q Series modules, and using
the existing wiring terminal block with the conversion adapter.
(Example) A1SX20 -> QX28 x 2 modules, A1SY60(E) -> QY68A x 2 modules
