Specification

SEODescription

The Mitsubishi Q24DHCCPU-VG-B002 is a high-performance redundant CPU module designed for mission-critical industrial automation systems. As part of the Redundant CPU PLC system, this High-speed control module VG features dual CPUs operating in synchronization, enabling seamless failover during critical operations. It supports direct connection to up to 64 I/O modules with a base unit, offering flexible expansion capabilities. The module integrates multiple communication interfaces including Ethernet, MELSECNET/H, and serial ports for seamless integration with factory networks. Operating within a 24V DC ±10% voltage range and a temperature tolerance of 0–55°C, it ensures reliability in harsh environments. Widely used in power generation, chemical processing, and continuous manufacturing industries, its key advantages include ultra-fast 1ns processing speed, dual redundancy for zero downtime, and robust error diagnostics. However, its complex configuration requires specialized programming expertise, and the redundant architecture increases overall system cost compared to standard PLC solutions.
