Mitsubishi MELSEC Q Q35B Base Unit Rack

Mitsubishi MELSEC Q Q35B Base Unit Rack

The Mitsubishi MELSEC Q35B is a 3-slot main base unit designed for the high-performance MELSEC Q Series Programmable Logic Controller (PLC) system. It serves as the foundational backbone, providing the physical mounting and electrical connectivity for the system’s core components, such as the power supply module and CPU module.

As a critical component of a modular PLC system, the Q35B allows for the flexible and scalable construction of automation control systems to meet a wide range of application requirements.

Key Features

• 3-Slot Capacity: Provides space to mount three modules (e.g., a power supply, a CPU, and one additional I/O or intelligent module), making it ideal for compact but expandable system configurations.

• Main Base Unit: Designed to hold the system’s primary modules, including the Q61P/Q62P/Q63P Power Supply and the Q Series CPU (e.g., Q00J, Q02H, Q03UD, etc.). The CPU and Power Supply must be mounted in their designated positions on this base.

• High-Speed System Bus: Integrates seamlessly with the Q Series’ high-speed system bus, enabling rapid data exchange between the CPU, I/O modules, and intelligent function modules (like motion controllers, network modules, and analog I/O).

• Robust DIN Rail or Panel Mounting: Can be easily installed on a standard DIN rail (TH35-7.5Fe) or directly mounted to a panel, offering flexibility for various cabinet designs.

• Module Fixing Lever: Includes secure locking levers to ensure all modules are firmly connected to the base unit, preventing disconnection due to vibration or shock in industrial environments.

• Expansion Capability: The system can be expanded by connecting extension base units (like the Q65B or Q68B) via extension cables, allowing for the addition of numerous I/O points and special function modules.

Technical Specifications

Application Examples

The Q35B base unit is the starting point for building a robust and reliable PLC system in a wide array of industrial automation scenarios, including:

• Factory Automation (FA): Machine control, conveyor systems, assembly lines.

• Process Control: Monitoring and controlling temperature, pressure, and flow.

• Packaging Machinery: Coordinating complex sequences and servo motion.

• Material Handling: Controlling sorting systems and automated storage/retrieval systems (AS/RS).

• Infrastructure Management: Building automation, water treatment control.
