R04CPU MELSEC iQ-R Series Sequencer CPU module for iQ-R series PLC

Mitsubishi Electric's scalable, low-cost CPU modules are ideal for realizing affordable standalone control systems that require fewer I/O. Unlike standard CPU modules, these modules are redesigned to include non-volatile memory and do not require a separate backup battery. They also have an embedded Ethernet port as a standard feature, thereby supporting seamless network connectivity with other devices via CC-Link.


• Supports up to 4,096 I/O points.
• Controlled via stored program cyclic operation.
• Scans from 0.2 to 2000 ms.
• No backup battery necessary.
• SD memory cards available up to 16GB.
• Ethernet for easy networking.
• Small size to fit into any control cabinet.
