Q Series Large Type Base Unit

Supported series:

Q Series large type base unit (AnS Series size)

The Q Series large type base unit is used to replace the AnS Series module with the Q Series, using the existing installation area and cables.

• Utilizing a 16-point terminal block from the existing AnS/QnAS Series module reduces the rewiring work.
• When replacing the AnS/QnAS Series module with the Q Series by using the conversion adapter (Upgrade tool products by Mitsubishi Electric Engineering Co., Ltd.) and the existing AnS/QnAS Series terminal block without rewiring, the width of I/O slot of this base unit is just the same as the existing wide-sized AnS/QnAS Series, then the space reduces noise interference from nearby modules.^*1
• The installation position is the same as the AnS/QnAS Series, and the installation holes can be used to install the Q Series large type base unit.
• Q Series large type base units (AnS Series size) for panel installation and DIN rail installation are available. Select the type for your need.

*1.The Q Series large type blank cover QG69LS (selling separately) is required with the Q Series I/O module.

[Example] Replacing AnS/QnAS Series module with Q Series module using conversion adapters and Q Series large type base unit

1. (1)Remove the AnS/QnAS Series module along with the base unit, install the Q Series large type base unit in the same position using the same installation holes, and install the Q Series modules. (No need of making new installation holes when installing the Q Series large type base unit.)
2. (2)Attach the Q Series large type blank cover (AnS Series size) to the Q Series module and install the Q Series module to the Q Series large type base unit.
3. (3)Attach the conversion adapter (Upgrade tool products) to the Q Series module with the Q Series large type base unit.
4. (4)Remove the terminal blocks from the existing AnS/QnAS Series module and attach them to the conversion adapter.
   (The existing wiring can be used without modification.^*2)

1. *2.Partial change in wiring for the power supply and common terminals is required.
2. *3.Provided with screw holes for fixing the conversion adapter support flange.

Q Series large type base unit (AnS Series size) list

The following base units are available to use the Q Series modules with the installation holes of the AnS/QnAS Series modules. DIN rail can also be used. The width of I/O slots of this base unit is the same with that of the existing wide-sized AnS/QnAS Series, minimizing the interference from nearby modules.^*4

*4.To install the Q Series module on the I/O slot of the Q Series large type base unit, always attach the Q Series large type blank cover QG69LS (sold separately).
