The CP461-51 is a high-performance central processing unit designed as the primary intelligence module for Yokogawa CENTUM VP Field Control Units (FCU). Featuring a dual-core ARM Cortex-A57 architecture, this module provides the computational power required for real-time process control, complex regulatory loops, and sequence logic execution. With a 2.0 GHz clock speed, the CP461-51 delivers near-instantaneous response for industrial automation tasks.
As a “Standard Type” (-51) module, it does not include explosion protection and is optimized for installation in climate-controlled control rooms or non-hazardous rack environments. The CP461-51 is engineered for high availability and supports dual-redundant CPU pairing, ensuring uninterrupted plant operations in the event of hardware failure. Compatibility with industrial real-time operating systems such as VxWorks ensures deterministic execution for mission-critical automation workloads.

What is the difference between CP461-51 and CP461-E1?
The CP461-51 is the standard industrial version for general use, while the E1 variant typically includes enhanced compliance certifications or specialized hardware revisions for specific regional or application requirements.
Is the CP461-51 hot-swappable?
Yes. In dual-redundant FCU configurations, a single CP461-51 can be replaced while the secondary processor continues to control the process without downtime.
