Product Overview
The AFV30D-S41252 is a high-availability Field Control Unit (FCU) designed for the Yokogawa CENTUM VP R6 Distributed Control System (DCS). As the central processing hub for both Vnet/IP and FIO architectures, it executes real-time control logic while coordinating communication across plant-wide networks.
Built with a duplexed “Pair & Spare” architecture, this unit ensures continuous and fault-tolerant operation in mission-critical environments. It incorporates redundant communication interfaces and power supply modules, effectively eliminating single points of failure and maintaining uninterrupted process control.

Industrial Applications
The AFV30D-S41252 is widely used in large-scale, high-reliability DCS installations where continuous operation is critical.
Typical applications include LNG terminals, chemical processing plants, and thermal power stations. Its ability to manage high-density I/O while maintaining deterministic communication over Vnet/IP makes it ideal for distributed control architectures requiring long-distance networking and real-time synchronization.
Technical Integration FAQ
Does this unit support older CENTUM VP versions?
This model is specified for CENTUM VP R6.01 or later. Compatibility with earlier versions (such as R5) should be confirmed based on firmware and system configuration.
Is the power supply redundant?
Yes. The unit includes dual-redundant 220–240 V AC power modules, ensuring continuous operation even if one power source fails.
What is the difference between the “-S” and “-A” versions?
The “-S” suffix denotes the standard configuration optimized for CP461 processors, while other variants (such as “-A”) may differ in processor compatibility, power specifications, or environmental ratings.
