AFV10D-S41401 | Yokogawa | Duplexed Field Control Unit DCS

Brief Product Description

The Yokogawa AFV10D-S41401 is a high-availability Duplexed Field Control Unit (FCU) designed for the CENTUM VP Distributed Control System. This unit serves as the intelligence center for Field Control Stations, integrating Vnet/IP communication and FIO (Field I/O) subsystems. Engineered for mission-critical processes, the AFV10D-S41401 utilizes dual-redundant hardware and a RISC-based processor to ensure continuous plant operation even in the event of a component failure.

Product Description

Mission-Critical Control and Redundancy

The Yokogawa AFV10D-S41401 (S2 series) is the core controller within the CENTUM VP architecture. It is specifically designed to handle high-speed logic execution and complex regulatory control. The "Duplexed" designation indicates that the unit contains dual-redundant processor modules operating in parallel; if the primary unit encounters an error, control is bumplessly transferred to the standby unit within milliseconds.

Equipped with a 133 MHz RISC processor and 32 MB of main memory, the AFV10D-S41401 is optimized for low-latency communication over Vnet/IP. This digital network allows for robust data exchange between the FCS and Human Interface Stations (HIS). The unit is housed in a 19-inch rack-mountable chassis, providing a standard form factor for seamless integration into existing control room cabinets.
