Yokogawa CP401-11 | C2KC03014H | CENTUM VP Processor Module

Product Overview

The CP401-11 (Part Number: C2KC03014H) is a high-availability Field Control Station (FCS) processor module engineered for Yokogawa’s CENTUM VP and ProSafe-RS control systems. It serves as the core computational unit for real-time control logic, managing critical process data and high-speed communications across the Vnet/IP network.

The module incorporates Yokogawa's signature "Pair & Spare" technology. This dual-microprocessor architecture performs continuous cross-checks of calculations, ensuring that hardware discrepancies are detected instantly. This mechanism allows the CP401-11 (C2KC03014H) to maintain Safety Integrity Level 3 (SIL3) compliance, making it an essential component for safety-instrumented systems (SIS) and mission-critical distributed control environments.
