AFV10D-F1

The Yokogawa AFV10D-F1 is a duplexed Field Control Unit (FCU) for the CENTUM VP distributed control system. It executes control functions, manages field I/O data, and communicates with the control network through Vnet/IP. The unit supports a 19-inch rack-mounted configuration and redundant processor and power supply arrangements. Its interface, power supply, memory backup, and environmental requirements should be verified when selecting a replacement or configuring an existing control station.

Control Functions and Redundancy

The FCU forms the processing core of a Field Control Station (FCS). It executes configured control logic and exchanges process data with field I/O equipment. The duplexed architecture provides redundant processing and power supply paths; actual failover behavior depends on the installed hardware configuration and system setup.

Vnet/IP and Field I/O Connectivity

The unit is specified for dual-redundant Vnet/IP communication at 1 Gbps full duplex. The supplied network requirements specify CAT5e or better UTP cabling with RJ45 connectors and a maximum cable length of 100 m. Node capacity is specified as up to 14 nodes per FCU, including up to 9 ESB bus node units.

The status contact provides NC and common terminals for external status monitoring, with the connected circuit limited by the stated contact rating.

Frequently Asked Questions

Q: Does the AFV10D-F1 support redundant control processing?

A: The supplied specifications describe dual-redundant processors and power supplies. Confirm the installed hardware and configured control system before assuming a particular failover behavior.

Q: What network cable can be used with this unit?

A: The supplied data specifies CAT5e or better UTP cable with RJ45 connectors, with a maximum cable length of 100 m. Verify the applicable network installation requirements for the installed CENTUM VP configuration.

Q: Can the unit be powered directly from 24 V DC?

A: The supplied specifications list 24 V DC as a power supply option, with a stated consumption of 5.5 A. Confirm the complete model code and power supply configuration before ordering or replacing the unit.
