Description

Engineered for high-availability industrial control architectures, the Q25PRHCPU is a high-performance redundant CPU module belonging to the Mitsubishi Electric MELSEC-Q Series platform. This controller is designed to mitigate system downtime by supporting hot-standby redundant configurations, making it suitable for continuous process applications. Operating under a stored program cyclic execution method with refresh-mode I/O control, it delivers reliable execution of complex sequence and process control logic.

The Q25PRHCPU features a generous 252K-step program capacity and integrates a versatile memory card interface compatible with SRAM, Flash, and ATA cards. Processing efficiency is highlighted by an ultra-fast instruction execution speed of 34 ns for basic LD instructions and 102 ns for MOV instructions. With its broad instruction set and robust physical construction, this redundant processor ensures seamless system integration and maximum process continuity.

Features

Redundant system architecture to prevent operational shutdowns in critical applications.
Rapid execution speeds with 34 ns LD instruction and 0.78 us floating-point addition times.
Large-scale logic processing capacity supporting up to 252K program steps.
Flexible memory expansion via dedicated SRAM, Flash, and ATA memory card interfaces.
Supports both sequence control and process control programming languages for versatile application deployment.
Constant scan settings configurable from 0.5 ms to 2000 ms in 0.5 ms increments.

Applications

Power generation and distribution control systems.
Water and wastewater treatment facilities.
Continuous chemical and petrochemical processing plants.
Large-scale infrastructure and HVAC control networks.
