The Mitsubishi R04CPU is a MELSEC iQ-R Series programmable controller CPU module designed for modular PLC systems in industrial automation environments. With 40K steps of programme memory, it provides a compact and capable processing platform for machine control, production line automation and system integration tasks.
This standard CPU module supports up to 4,096 local I/O points and up to 12,288 combined local and remote I/O points, making it suitable for scalable control architectures. Built-in USB and Ethernet connectivity allow convenient connection to compatible devices and networks, while the integrated buffer battery supports data retention for clock and memory functions.
Measuring approximately 27.8 mm wide, 106 mm high and 110 mm deep, the R04CPU offers a space-saving format for installation within Mitsubishi iQ-R rack-based control systems. Its fast processing performance, including LD cycle time of 0.98 ns and MOV cycle time of 1.96 ns, makes it well suited to applications requiring responsive and reliable PLC operation.

What type of module is this?
It is a programmable controller CPU module for MELSEC iQ-R modular PLC systems. It is designed to act as the central processing unit in an automation rack, managing logic execution, connected I/O and communications.
How much programme capacity does it provide?
The R04CPU provides 40K steps of programme memory, making it suitable for compact to mid-sized control applications within an iQ-R platform.
What communication interfaces are built in?
The module includes one Ethernet port and one USB interface. These interfaces are commonly used for controller communication, configuration access and integration with connected automation equipment.
How many I/O points can the controller handle?
It can handle up to 4,096 local I/O points and up to 12,288 combined local and remote I/O points, depending on the full system configuration.
What are the physical dimensions of the CPU module?
The module measures approximately 27.8 mm wide, 106 mm high and 110 mm deep. Some listings may reference a height of 98 mm or 106 mm depending on the measurement convention used.
Does the module include battery backup?
Yes. The controller uses a buffer battery arrangement for retaining clock data and memory functions as required by the system. The associated spare battery listed for this module is Q6BAT.
What is the internal current consumption?
The internal current consumption is 0.67 A. This should be considered when calculating the power requirements for the complete iQ-R rack.
