IS72S-0.75K MITSUBISHI Basis unit

Product  Description：

A Mitsubishi Base Unit, often referred to as a Main Base or Backplane, is the foundational hardware component of a modular PLC system such as the MELSEC iQ-R, Q, or L series. It acts as the physical and electrical backbone, providing the slots into which the Power Supply, CPU, and various I/O or functional modules are inserted. Its primary role is to facilitate high-speed data communication and power distribution across the entire controller rack.

Product Parameters

The technical configuration of a Mitsubishi Base Unit is defined by its expansion capacity and electrical integrity:

• Number of Slots: Available in various sizes, typically supporting 3, 5, 8, or 12 slots for mounting different modules.

• Bus Speed: Features a high-speed internal bus system (such as the iQ-R high-speed system bus) capable of multi-gigabit data transfer rates between the CPU and intelligent modules.

• Extension Port: Many units include an extension cable interface to connect to "Extension Base Units," allowing the system to expand across multiple racks.

• Installation Method: Equipped with standard DIN rail mounting hooks and specialized screw holes for secure attachment to control panels.

• Internal Current Consumption: Specifically rated to handle the total current draw from the power supply module to all connected modules on the backplane.

• Dimensions: Optimized for standard rack widths (e.g., 19-inch standards or compact industrial footprints) to fit within shallow electrical cabinets.

Product Advantages

Mitsubishi Base Units are designed for high-performance industrial environments with several distinct benefits:

• Superior Signal Integrity: The backplane is engineered with advanced shielding to prevent signal crosstalk between high-speed communication lines and digital I/O.

• Mechanical Rigidity: Built with high-quality materials to resist warping and ensure that modules remain securely seated even in high-vibration environments like mobile machinery.

• Tool-less Module Installation: Features a "hook and lock" mechanism that allows modules to be swapped quickly without the need for complex tools, reducing downtime.

• High Expansion Flexibility: By utilizing extension units, a single CPU can manage a massive distributed system with hundreds of modules connected via a unified base architecture.

• Integrated Grounding: Includes a dedicated grounding terminal (LG/FG) integrated into the bus structure to simplify the process of stabilizing the system's electrical potential.

Product Applications

The Base Unit is the starting point for any modular Mitsubishi automation project:

• Complex Machine Control: Used in large-scale assembly lines where dozens of I/O and motion modules must be synchronized by a central processor.

• Distributed Control Systems (DCS): Acting as the local node for managing remote sensors and actuators in chemical processing or water treatment plants.

• Data Logging Hubs: Providing the physical framework for high-speed data collection modules used in quality control and predictive maintenance.

• Safety Systems: Hosting specialized safety CPUs and safety I/O modules to create a SIL3-rated protection environment for hazardous machinery.

• Automotive Production: Providing the backbone for the heavy-duty control panels used in vehicle stamping and painting shops.

Important Precautions

To ensure long-term system stability, the following operational guidelines should be followed:

• Slot Configuration: Always install the Power Supply module in the leftmost dedicated slot and the CPU in the slot immediately following it, as specified by the hardware manual.

• Dust Protection: If any slots on the base unit are left empty, they must be covered with a "Dummy Module" or slot cover to prevent dust and debris from contaminating the bus connectors.

• Extension Cable Length: When using extension base units, do not exceed the total specified length for extension cables (usually 13.2 meters for certain series) to avoid signal degradation and communication errors.

• Secure Mounting: Ensure that the base unit is mounted on a flat surface. Any bending or torsion applied to the backplane during installation can cause intermittent connection issues between modules.

• Power-Off Installation: Never insert or remove modules from the base unit while the power supply is turned on. This can cause electrical arcing, which may damage the sensitive pins on the backplane connector.
