R08CPU MELSEC iQ-R CPU Unit 80K Steps Ethernet | Mitsubishi

The Original New Mitsubishi R08CPU is a standard programmable logic controller (PLC) CPU unit from the MELSEC iQ-R series, designed for medium-scale machine automation and process control systems. It provides 80K steps (320 KB) of program memory, 1,188 KB of device/label memory, and 5 MB of data memory, with a basic instruction processing speed of 0.98 ns (LD instruction) and 1.96 ns (MOV instruction). Built-in USB 2.0 and Ethernet ports offer flexible programming and network communication options, while the integrated CC-Link IE Field Basic capability supports distributed I/O architectures without additional communication modules. The R08CPU is designed for high-speed processing, data logging, and real-time monitoring applications across factory automation, material handling, and production line control.
