The Yokogawa AFV10D-S41151 Duplexed Field Control Unit (FCU) is an advanced, high-reliability control device designed for industrial distributed control systems (DCS) and automation networks requiring fault-tolerant operation. As a duplexed unit, it features dual redundant channels, ensuring uninterrupted control of critical process loops even in the event of a hardware failure.

Part of the AFV10D series, the AFV10D-S41151 integrates seamlessly with Yokogawa CENTUM VP or other compatible DCS platforms. It provides precise field device control, fast data acquisition, and secure communication. The duplexed architecture allows one channel to act as a backup to the active channel, maintaining continuous operation without any process disruption.

This FCU is widely used in petrochemical, oil and gas, power generation, water treatment, and industrial automation applications where operational safety, process reliability, and high-speed response are critical. Its robust construction and fault-tolerant design ensure high signal integrity and accurate control under demanding industrial conditions.
