Yokogawa AFV10S Field Control Unit

AFV10S is Yokogawa’s Field Control Unit for Vnet/IP and FIO in a 19-inch rack-mountable Field Control Station. It connects the FCS with the applicable ESB/ER bus Node Units; the complete suffix, LFS1500 control function and installed CENTUM configuration must match before use.

AFV10S is specified for dual-redundant Vnet/IP with FIO and a 19-inch rack-mountable installation. Confirm the Vnet/IP buses, FIO/Node Unit arrangement, ESB or ER bus connections and the exact suffix because AFV10S is not a standalone generic I/O rack.

The Yokogawa specification requires the LFS1500 Control Function for the Field Control Station. For the cited turbomachinery I/O configuration, AFV10S supports up to 8 modules (4 dual-redundant sets) and 4000 words/FCS; the LFS1550-V11 Node Expansion Package can extend this to up to 16 modules (8 sets).

AFV10S suffix codes distinguish 100–120 V AC, 220–240 V AC or 24 V DC power and basic, ISA Standard G3 or explosion-protection options. Order and compatibility checks must use the complete coded suffix rather than the base model alone.

Confirm the full nameplate and style, 19-inch rack position, selected supply, grounding, Vnet/IP/FIO wiring, Node Unit and ESB/ER bus connections, LFS1500 function, ambient conditions and shutdown/backup record. If modules with built-in barriers are installed, Yokogawa specifies insulating partition kit T9083ND.

For SEM on Vnet/IP, Yokogawa states that AFV10S should be style 2 or later. Verify the style number on the component tag and check the SEM and CENTUM release requirements before commissioning; do not infer compatibility from the base model alone.

Provide the complete AFV10S suffix, style/revision, power and protection codes, LFS1500 function, installed FCS and rack position, Vnet/IP/FIO and Node Unit photographs, quantity and destination. Use the official Yokogawa GS 33K50E30-50E datasheet to confirm the ordered configuration.
