Product Introduction

The Yokogawa AFV30D-A41452 Duplexed Field Control Unit (FCU) is a high-reliability, duplexed control device designed for distributed control systems (DCS) and industrial automation environments requiring fault-tolerant operation. Its duplexed architecture ensures uninterrupted process control by providing dual redundant channels, making it ideal for mission-critical industrial operations.

Part of the AFV30D series, the AFV30D-A41452 integrates seamlessly with Yokogawa CENTUM VP and other compatible DCS platforms. It delivers precise control over field devices, high-speed data acquisition, and robust communication. The duplexed design allows one channel to serve as a backup for the active channel, ensuring continuous operation without process interruption.

This FCU is commonly deployed in petrochemical facilities, oil and gas plants, power generation stations, water treatment facilities, and other industrial sectors requiring high reliability, fast response, and advanced diagnostic capabilities. The AFV30D-A41452 provides deterministic control, operational safety, and enhanced monitoring for all critical process loops.
