FR-A840-450K-CHT MITSUBISHI

FR-A840-450K-CHT MITSUBISHI Basis unit 

Product  Description：

The Basis Unit is a high-performance backplane designed to house the essential components of an automation system. It features a specific number of slots—ranging typically from 3 to 12—which provide the internal data bus and power distribution for all mounted modules. Its rugged design ensures high reliability in industrial environments, facilitating high-speed data transfer between the CPU and intelligent function modules.

Product Parameters

While specific parameters vary depending on the model (such as the Q38B or R310B), the general specifications for these units include:

• Number of Slots: Available in configurations of 3, 5, 8, or 12 slots for mounting I/O and functional modules.

• Power Supply Slot: Dedicated slot specifically for the system power supply module.

• CPU Slot: Specialized slot(s) designed to hold one or more CPU modules for multi-processor configurations.

• Mounting Method: Standard DIN rail mounting or direct screw mounting via four corner holes.

• Internal Current Consumption: Typically ranges between 0.11A and 0.23A depending on the size and series.

• Extension Capability: Includes a connector for extension cables to link to "Extension Base Units" if more slots are required.

Product Advantages

The Mitsubishi Basis Unit offers several key benefits for industrial automation:

• High-Speed Communication: The integrated backplane bus allows for near-instantaneous data exchange between the processor and the I/O modules, reducing scan times.

• Modular Scalability: Users can easily expand their system by choosing a base unit with more slots or by daisy-chaining extension bases.

• Durability: Built to withstand vibration, shock, and electromagnetic interference commonly found in factory floors.

• Ease of Maintenance: Modules can be swapped out relatively easily, and the rigid structure ensures secure mechanical connections that don't loosen over time.

• Compact Footprint: It optimizes panel space by consolidating power, logic, and I/O into a single, organized unit.

Key Considerations and Precautions

To ensure optimal performance and safety, keep the following points in mind:

• Power Loading: Ensure the power supply module mounted on the base can handle the total current consumption of all other modules plugged into that specific base.

• Slot Constraints: Certain modules (like high-speed counters or motion controllers) may have specific slot requirements; always check the CPU manual for slot compatibility.

• Installation Environment: Avoid installing the unit in areas with excessive conductive dust, corrosive gas, or high temperatures, as these can degrade the backplane contacts.

• Grounding: The base unit must be properly grounded via the "Functional Ground" terminal to prevent electrical noise from interfering with logic signals.

• Extension Cable Length: When using extension bases, total cable length must stay within the manufacturer's limits to prevent data loss or timing errors.

Product Applications

Mitsubishi Basis Units are utilized across a wide array of industries:

• Automotive Assembly: Managing complex robotics and conveyor systems on assembly lines.

• Water Treatment: Controlling pumps, chemical dosing, and filtration cycles.

• Packaging Machinery: Coordinating high-speed labeling, filling, and wrapping processes.

• Semiconductor Manufacturing: Handling precision environment control and wafer transport.

• Building Automation: Integrating HVAC, lighting, and security systems in large-scale facilities.
