Yokogawa AFV30D-S41152 Duplexed Field Control Unit

Product Introduction

The Yokogawa AFV30D-S41152 Duplexed Field Control Unit (FCU) is a high-performance, redundant control module designed for use in CENTUM VP Distributed Control Systems. As part of Yokogawa’s advanced field control architecture, this model is engineered to ensure continuous process operation, high fault tolerance, and seamless system integration.

The duplexed design allows two CPUs to operate simultaneously in a redundant configuration, meaning if one CPU fails, the other takes over instantly without any process interruption. This makes the AFV30D-S41152 an indispensable solution for mission-critical industries such as oil & gas, petrochemicals, power generation, and large-scale manufacturing.

The unit is built to deliver deterministic real-time control, reliable networking through Vnet/IP, and support for large-scale I/O expansions. By providing long-term stability and system compatibility, it ensures that plant operators can achieve the highest levels of safety, efficiency, and availability.
