Yokogawa CP451-50 S2 CPU Module

>> Key Advantages & Features

• High-Speed Processing Capability

Equipped with a 1.2 GHz multi-core processor, the module executes 64-bit control logic at a rate of 100,000 steps per millisecond—30% faster than previous generations. This speed enables precise control of complex processes, such as multi-loop temperature regulation in chemical reactors, ensuring tight process tolerance within ±0.1°C.

• Scalable System Integration

Supports up to 4096 I/O points and 1000 control loops, with expandable memory (8 GB RAM, 64 GB flash) for large program storage. It seamlessly integrates with Yokogawa’s ProSafe-RS safety system and field devices via FOUNDATION Fieldbus, HART, and PROFINET, reducing integration time by 25% in retrofitted plants.

• Enhanced Reliability with Redundancy

Offers dual-redundant configuration with automatic failover (switchover time <50 ms), achieving 99.999% availability. This design ensures uninterrupted operation in critical applications like offshore oil platform control, where downtime could cost millions in production losses.

• Advanced Diagnostic & Cybersecurity

Features real-time self-diagnostics for hardware faults, communication errors, and process anomalies, with alerts displayed on CENTUM VP’s HMI. Incorporates IEC 62443-compliant security measures (role-based access, encrypted communication) to prevent unauthorized access—vital for protecting critical infrastructure.

• Energy-Efficient Operation

Optimized power consumption (max 30 W) reduces heat generation by 20% compared to modules, extending component lifespan and lowering cooling costs in control rooms. Its fanless design minimizes maintenance needs in dust-prone environments like mining facilities.
