Product Description

The A0J2HCPU is an integrated CPU that combines the processor, power supply, and I/O base functionality into a single unit. As an evolution of the original A0J2 series, the “H” version (High-speed) provides significantly faster instruction processing and expanded memory capacity. It is specifically built for users who need the reliability of the MELSEC-A series in a space-saving form factor, supporting both local and remote I/O expansion.

Product Parameters

• Control Method: Stored program cyclic operation

• I/O Points: Up to 480 points (Total of local and remote I/O)

• Program Capacity: 8k steps (RAM/EPROM/EEPROM options)

• Instruction Execution Speed: 1.25 microseconds per sequence instruction

• Memory Type: Built-in RAM with battery backup; optional ROM (EPROM/EEPROM)

• Communication Ports: RS-422 for programming and HMI connection; supports MELSECNET/MINI for remote I/O

• Internal Relay (M): 2048 points

• Data Register (D): 1024 points

• Timer (T): 256 points

• Counter (C): 256 points

• Power Supply: Integrated (Typically 100-240V AC or 24V DC depending on the specific sub-model)

Product Advantages

• Compact Integration: By combining the power supply and CPU, it reduces the required cabinet space and simplifies installation compared to modular PLC systems.

• Enhanced Performance: The “H” series offers faster processing speeds than standard A0J2 models, allowing for better handling of complex logic and arithmetic operations.

• Reliable Legacy Support: It is known for its extreme durability and long service life, making it a staple in factories that require consistent operation over decades.

• Expandability: Despite its compact size, it can be expanded using the MELSECNET/MINI network, allowing for distributed control architectures.

• Proven Stability: As part of the MELSEC-A lineage, it utilizes a highly stable instruction set that is well-documented and widely understood by automation engineers globally.

Important Considerations

• Lifecycle Status: The A0J2HCPU is a legacy (discontinued) product. While it is widely available in the secondary and spare parts market, it is no longer recommended for new installations.

• Battery Maintenance: The internal RAM relies on a lithium battery for data retention. If the battery fails, the program and parameters will be lost. Regular battery replacement cycles (typically every 3-5 years) are essential.

• Programming Software: It requires legacy Mitsubishi software (such as GX Developer or MEDOC). Ensure you have the correct serial communication cables (SC-09 or equivalent) for interfacing.

• Heat Dissipation: Due to the integrated power supply, the unit can generate heat. Ensure adequate clearance around the unit for air circulation within the control panel.

Product Applications

The A0J2HCPU is commonly found in older automated systems, including:

• Conveyor Systems: Managing logic for material sorting and distribution lines.

• Plastic Injection Molding: Controlling basic heating, clamping, and injection sequences.

• Textile Machinery: Overseeing weaving, spinning, and fabric processing equipment.

• Building Automation: Managing lighting, ventilation, and small-scale pump control in commercial buildings.

• Machine Tools: Serving as the controller for dedicated drilling or grinding machines.
