The Mitsubishi iQ-R series R08PCPU and R16PCPU represent the pinnacle of programmable controller performance, engineered for high-speed, reliable control in complex industrial environments. These CPU modules utilize a stored program cyclic operation method, ensuring deterministic execution of logic. With support for ladder diagrams, structured text, function block diagrams, and sequential function charts, the R08PCPU and R16PCPU offer unparalleled flexibility for system engineers. The I/O control mode employs a refresh system with direct access I/O capability (DX, DY) for real-time response. Both models feature a constant scan function adjustable from 0.5 ms to 2000 ms in 0.1 ms increments, maintaining consistent cycle times. The R08PCPU and R16PCPU are designed to handle up to 4096 I/O points, making them ideal for mid-to-large scale automation projects.
