Description

Designed for high-speed, high-accuracy automation environments, the Mitsubishi Electric Q04UDHCPU functions as a highly capable processing core within the MELSEC Q series PLC platform. This Universal model CPU module delivers rapid sequence execution and ample program memory, making it suitable for multi-axis motion control, complex assembly systems, and demanding industrial processing applications.

The unit features an integrated program capacity of 40K steps (160K bytes) and processes basic instructions in as little as 9.5 nanoseconds. For communication and programming, the module is equipped with dedicated onboard USB and RS-232 serial interfaces, alongside a standard slot for memory expansion cards (SRAM, Flash, or ATA). This configuration ensures seamless integration with HMIs, external networks, and engineering software packages like GX Works2 or GX Works3.

Features

Highly rapid processing times with sequence instruction execution down to 9.5ns.
Generous program storage capacity of 40K steps to handle complex control logic.
Support for versatile programming approaches, including Ladder, Structured Text (ST), Function Block (FB), and Sequential Function Chart (SFC).
Built-in dual peripheral connection ports utilizing USB and RS-232 interfaces.
Onboard expansion slot accepting SRAM, Flash, and ATA memory cards.
Large capacity configuration with up to 8192 total direct/refresh I/O points.

Applications

Automotive assembly lines and robotic work cell coordination.
High-speed packaging, labeling, and sorting machinery.
Water and wastewater treatment processing installations.
Semi-conductor manufacturing and chemical batch processing plants.

Installation Guidelines

Always mount the module securely onto a compatible MELSEC Q series base unit. Ensure the mounting locking mechanism is fully engaged before applying power.
Ensure all system power is switched off before installing, removing, or wiring any module in the rack assembly.
Ground the system via the Protective Earth (PE) and Functional Earth (FG) terminals on the main power supply module of the base rack using 2 mm square or thicker copper wire.
Maintain adequate clearance (minimum 30mm) around the top, bottom, and sides of the CPU assembly to allow optimal convection cooling and prevent thermal derating.

Compliance and Certifications
