The Yokogawa CP461-50 is a high-performance Processor Module specifically engineered for the CENTUM VP Distributed Control System (DCS). Designed as the primary logic solver for Field Control Units such as the AFV300 and AFV400, this module executes complex regulatory and sequence control strategies with real-time precision. The CP461-50 serves as the modern, standardized replacement for the legacy CP461-10 module, offering improved processing efficiency and long-term hardware support for mission-critical automation infrastructures.
The CP461-50 is built for high-availability environments, supporting dual-redundant configurations to eliminate single points of failure. In a redundant setup, two modules operate in parallel, ensuring that control is maintained without interruption should one unit require maintenance. It manages up to 8 I/O modules directly, coordinating high-speed data exchange via Yokogawa’s proprietary Vnet/IP control network alongside standard protocols like Modbus/TCP. Its rugged, compact design is optimized for control cabinet density while maintaining the thermal and vibration resistance required for harsh petrochemical and power generation settings.
