Programmable Controllers MELSEC-A Series Renewal
Principal replacement examples for updating are introduced.
Replace with the L/Q Series while utilizing the existing programs
Replace with the L Series while keeping the existing wiring
Replace with the Q Series CPU module while keeping the existing modules
Utilize the existing 32-point wiring I/O module with Q Series
Minimize wiring modifications by reusing the existing A Series 32-point I/O wiring.
No need to make new installation holes. The hole size and pitch of the Q Series large type base units are the same as those of A/QnA Series.
Install the Q Series base unit with the existing installation holes
Replace the system to Q Series while utilizing the existing wiring
The upgrade tool products consists of three components: a conversion adapter, which modifies the existing wiring of the A/QnA Series input/output/analog/high-speed counter modules to correspond to the Q Series modules; a conversion adapter support flange, which supports the conversion adapters from the bottom, and a base adapter, which allows the Q Series base unit to be installed using the installation holes of the A/QnA Series base unit. (The upgrade tool products does not include the Q Series base unit. Please prepare it separately.)
The upgrade tool products consists of the following three parts:
- a conversion adapter, which enables utilization of the wiring, which was connected to the AnS/QnAS Series input/output/analog/high-speed counter/temperature input/temperature control module, with the Q Series module, - a base adapter, which enables a Q Series base unit installation using the installation holes of the AnS/QnAS Series base unit, and - a conversion adapter DIN rail mounting bracket, which enables the use of a conversion adapter with support flange (for a Q Series base unit) and a disconnection detection connector conversion cable (for a temperature control module).
Replace MELSECNET/MINI-S3 with CC-Link while utilizing the existing wiring
The simple replacement process helps minimize the upgrade time.
The installation size is the same as that of A2C I/O modules; existing terminal block can be installed directly.
Modules for easy replacement
- DC input module
- DC input module
- I/O combined module
- Relay output module
- Triac output module
- Temperature control module
- High-speed counter module
- Analog output positioning module
Utilize the existing network cables to build the MELSECNET/H(10) network system
Reuse the existing network cables to build MELSECNET/H network system.
- MELSECNET/H Network module (twisted bus type)
- MELSECNET/H Network module (optical loop type, coaxial bus type)
Replace A0J2(H) system with Q Series while utilizing the existing wiring
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.
