Yokogawa Electric Corporation CP461-11 S1 Processor Module

The Yokogawa CP461-11 S1 Processor Module is a rack-mounted central processing unit for the CENTUM VP Distributed Control System, executing control logic, managing real-time processes, and coordinating system operations from a control cabinet. As an industrial embedded processor system, it uses an integrated system bus to communicate with I/O and network modules, enabling reliable, synchronized automation across the DCS. It is backplane-powered and rated for 0°C to 55°C operating conditions, -20°C to 70°C storage, and 5% to 95% non-condensing humidity. Commonly deployed in oil and gas, chemical processing, power generation, and manufacturing environments, the CP461-11 S1 supports system control, replacement of failed CPUs, and upgrades or expansions of CENTUM VP infrastructure, with compatible replacements including the CP461-10 S1, CP451-11 S1, and CP345 S1.
