Description
YOKOGAWA AFV30D-A41152 – Duplexed Field Control Unit (FCU)
Product Overview
The AFV30D-A41152 is a high-reliability duplexed field control unit developed by Yokogawa, serving as the core processing and control component for the CENTUM VP DCS system. Adopting dual redundant processor and network architecture, this FCU undertakes on-site field signal acquisition, real-time logic computation, and inter-device linkage control tasks. It eliminates system downtime and data loss risks caused by single-point faults, supporting bumpless switching between master and standby units within milliseconds. The YOKOGAWA AFV30D-A41152 delivers stable, high-precision control performance and 7×24-hour fault-tolerant operation for continuous process industrial production.
