Specification

SEODescription

The Mitsubishi R04CPU module, part of the MELSEC Q series, is a compact PLC CPU designed for industrial automation. It features 16 digital inputs and 12 digital outputs, supporting direct expansion with up to 8 I/O modules via its base unit. The R04CPU offers versatile communication interfaces including RS-232, RS-485, and Ethernet for seamless integration into control networks. Operating within 24 VDC ±10% and a temperature range of -10°C to 55°C, it suits harsh environments in manufacturing, energy, and automotive industries. Key advantages include high reliability, modular flexibility, and compatibility with GX Works2 programming software. However, its limited memory capacity and lack of built-in analog I/O may require additional modules for complex applications. For detailed specifications, refer to the R04CPU datasheet PDF available on Mitsubishi’s official support portal.
