Product Description

The MELSEC Q25PRHCPU module is Mitsubishi PLC redundant CPU designed for high-reliability control systems, featuring a dual-CPU redundancy architecture to ensure uninterrupted operation. It supports up to 4,096 I/O points via direct connection to 64 base units and integrates multiple communication interfaces, including Ethernet, CC-Link IE, and serial ports. Operating at 24 VDC with a tolerance of ±10%, this module functions reliably within a temperature range of 0 to 55°C, suitable for critical industries like power generation, petrochemicals, and transportation. The Q25PRHCPU redundancy system enables seamless hot-swapping and synchronized data backup between primary and standby CPUs, minimizing downtime. Its advantages include robust fault tolerance and real-time diagnostics, while the limited scalability for older modules may require upgrades. The built-in battery offers extended backup (typically 5 years) for retaining program data during power loss.
