Description

Yokogawa CP401-10 S1 – Product Description & Technical Specifications
Product Description
The Yokogawa CP401-10 S1 is a control processor module, the S1 variant optimized for dual-redundant Field Control Station (FCS) applications in Yokogawa CENTUM VP and ProSafe-RS distributed control systems (DCS). It serves as the core processing unit, executing real-time process control logic, coordinating I/O subsystems via ESB/optical ESB bus, and enabling redundant communication with upper-level systems. Featuring a fanless natural convection design and Pair & Spare dual-CPU redundancy, it ensures seamless failover and 24/7 uninterrupted operation in mission-critical environments such as oil & gas, petrochemicals, power generation, and pharmaceuticals.
