FX2NC-64MT MITSUBISHI

FX2NC-64MT MITSUBISHI Basis unit

Product  Description：

The Mitsubishi Basis Unit, often referred to as a Main Base Unit or Backplane, serves as the physical and electrical foundation for the MELSEC programmable logic controller (PLC) systems, such as the System Q and iQ-R series. Its primary role is to provide the communication bus and mounting structure that links the power supply, CPU, and various I/O or functional modules into a single, cohesive automation system.

Technical Parameters

• Slot Capacity: Available in configurations ranging from 2, 3, 5, 8, to 12 slots for mounting modules.

• Mounting Method: Supports both direct screw mounting and DIN rail mounting using specific adapters.

• Operating Temperature: Standard industrial range typically from 0°C to 55°C.

• Internal Current Consumption: Varies by model, generally drawing a small amount of current from the power supply module to power the internal bus logic.

• Bus Speed: Features high-speed parallel bus architecture; some "DB" models support ultra-high-speed inter-CPU communication for multi-processor setups.

• Standards Compliance: Fully compliant with global standards including CE, UL, and cUL.

• Material: High-durability industrial plastics and metal grounding plates for electromagnetic interference (EMI) protection.

Product Advantages

• Modular Scalability: Users can choose a base unit size that fits their current needs while allowing for future expansion by simply adding more modules.

• High-Speed Communication: The integrated backplane bus ensures near-instantaneous data transfer between the CPU and I/O modules, reducing overall scan times.

• Robust Stability: Designed for harsh industrial environments, providing vibration resistance and reliable electrical connections that outperform "baseless" designs in high-vibration settings.

• Multi-CPU Support: Certain basis units allow for the installation of up to four different CPUs (e.g., PLC, Motion, Robot, and PC CPUs) to share the processing load.

• Simplified Maintenance: Modules can be swapped easily without rewiring the entire system, as the wiring is typically handled at the module level rather than the base.

Usage Precautions

• Slot Limitations: Ensure the power supply module is always installed in the leftmost dedicated slot; standard I/O modules cannot be placed in the CPU or power supply slots.

• Expansion Limits: When using expansion base units, the total length of the expansion cables must not exceed the maximum distance specified in the hardware manual to prevent signal degradation.

• Dust Protection: Any unused slots should be covered with a blank cover (dummy module) to prevent dust and debris from entering the bus connectors.

• Power Loading: Calculate the total current consumption of all modules to ensure they do not exceed the capacity of the power supply module mounted on the base.

• Grounding: The base unit must be properly grounded via the power supply module's ground terminal to ensure stable operation and protection against electrical noise.

Product Applications

• Automotive Assembly: Used to coordinate complex robotic arms and conveyors through multi-CPU synchronization on a single base.

• Food and Beverage: Controls high-speed packaging lines where rapid I/O processing is required for precision sorting and filling.

• Water Treatment: Manages large-scale distributed I/O systems across plants using expansion bases to monitor sensors and control pumps.

• Semiconductor Manufacturing: Provides the high-precision and high-speed logic necessary for wafer handling and cleanroom automation.

• Building Automation: Serves as the central control hub for HVAC, lighting, and security systems in large commercial infrastructures.
