CP461-51 | Yokogawa CENTUM VP CPU Module | New Made in Japan

Yokogawa CP461-51 Style S2 G3-Rated Processor Module

The CP461-51 (Model: CP461-51) is a high-availability central processing unit designed for the Yokogawa CENTUM VP and CS 3000 Field Control Stations (FCS). As the premium tier of the CP461 series, the CP461-51 (Style S2) features ISA Standard G3 conformal coating, providing superior protection against corrosive gases such as hydrogen sulfide and sulfur dioxide. This makes the module indispensable for harsh environments typical of wastewater treatment, oil refining, and chemical processing.

The CP461-51 (Part Number: CP461-51) utilizes a 32-bit RISC high-speed architecture clocked at 400 MHz, offering significant performance gains over earlier CP461-10 and CP461-11 versions. It serves as the primary execution engine for complex control logic, managing real-time data synchronization across the Vnet/IP network. With integrated thermal management and optimized circuitry, the Style S2 hardware ensures long-term component stability and deterministic process control in mission-critical applications.
