A0J2 Renewal Tool
Supported series: 
Replace A0J2(H) system with Q Series system using the existing wiring
A0J2 renewal tool features
The A0J2 renewal tool is used to replace the A0J2(H) system with the Q Series system. It consists of an interface module to which the existing wiring terminal block can be installed, and a base adapter that can be installed using the existing installation holes.
A variety of installation methods is available to fit the installation space.
Interface module features
The interface module has DC to relay output conversion and AC to DC input conversion functions. Hence, replacement is possible together with the Q Series connector type DC I/O modules.
Dedicated cables are used to connect the interface module to the Q Series I/O modules.
On-board installation
Suitable when there is enough depth. Stack the programmable controller on the existing panel face.
Note: Depth of 236 mm or more is required (when two interface modules are stacked).
Adjacent installation
Suitable when there is enough space above existing modules.
Install the programmable controller above the interface module(s).
Note:Space of 92 mm or more from the top of the existing modules is required.
Standalone installation
Install the programmable controller separately.
Note:For the AnS Series, the standalone installation only.
Structure [Example] 2-level on-board installation

- 1.When upgrading to the Q Series module, programs do not need to be modified if the I/O combined module "QX41Y41P (32-point input for the first half and 32-point output for the second half)" is used.
- 2.The A0J2 renewal tool can be used to replace the MELSECNET/MINI compact type I/O modules (AJ35PTF-□ (such as 28AR and 56DR)) with CC-Link modules.
