Description

Yokogawa CP401-10 – Product Description & Technical Specifications
Product Description
The Yokogawa CP401-10 is a control processor module designed for Yokogawa CENTUM VP and ProSafe-RS distributed control systems (DCS). It serves as the core processing unit of the Field Control Station (FCS), executing real-time process control logic, coordinating I/O subsystems, and enabling reliable communication with upper-level systems. This module supports dual CPU redundancy for fault-tolerant operation and features a fanless, natural convection design for silent and stable performance in critical industrial environments such as oil and gas, power generation, chemical processing, and pharmaceuticals.
