Description
YOKOGAWA CP461-50
The YOKOGAWA CP461-50 is a high-performance processor module designed for Yokogawa’s AFV300/AFV400 field control systems, serving as a direct replacement for the CP461-10. It acts as the central processing unit (CPU) for industrial automation, executing control algorithms, managing data flow, and coordinating with I/O modules. With support for dual-redundant configuration and a compact design, the CP461-50 ensures reliability in critical applications such as manufacturing, energy, and process control.

Advantages and Features
- Dual-Redundancy Design: Supports two modules for fault-tolerant operation, minimizing downtime in critical processes.
- High Processing Power: Efficiently handles real-time control of complex algorithms and data-intensive tasks.
- Scalability: Connects up to 8 I/O modules for flexible system expansion.
- Rugged Construction: Industrial-grade design (temperature range: -20°C to 70°C) for harsh environments.
- Easy Replacement: Direct substitution for CP461-10 with no reconfiguration required.
Application Areas and Cases
- Industries: Manufacturing, chemical processing, oil & gas, power generation.
- Case Example: A 建材 (building materials) production line integrated the CP461-50 with dual redundancy to control 8 I/O modules for conveyor systems and quality sensors. The module’s reliability reduced system failures by 20%, improving production efficiency and reducing maintenance costs.
Competitor Comparison
Compared to similar processor modules, the CP461-50 offers superior redundancy support (dual configuration as standard) and a higher I/O module capacity (8 vs. typical 6). Its compact size (15.2 cm depth) saves space in control cabinets, while direct compatibility with legacy CP461-10 systems minimizes retrofit costs.

Selection Recommendations
- System Compatibility: Ensure integration with AFV300/AFV400 systems.
- Redundancy Needs: Choose dual configuration for fault-critical applications.
- Environment: Verify temperature/humidity conditions match -20°C to 70°C (operating) and 0–90% RH.
- Scalability: Assess I/O module requirements (up to 8 modules).
Precautions
-
Installation: Follow electrostatic discharge (ESD) protocols; use shielded cables for signal integrity.
-
Power Management: Ensure stable 24V DC supply; avoid voltage fluctuations.
-
Maintenance: Replace batteries (e.g., HHR11F2A1) every 3–8 years (depending on temperature).
-
Firmware: Regularly update firmware via Yokogawa’s engineering tools for optimal performance.
-
Safety: Disconnect power before module replacement; follow IP ratings for environmental protection.
