Product Introduction
Controller mismatches are where DCS replacements become risky. The is a YOKOGAWA CENTUM VP/CS 3000 duplex field control unit, designed as the core controller for field control stations. It supports dual-redundant Vnet/IP communication and dual-redundant power supply, helping maintain control continuity during network or power faults.
For maintenance and procurement teams, this unit is typically used as an OEM replacement for aging or failed FCUs. The suffix code confirms 220–240 V AC power, non-explosion-proof construction, and LFS1700 control function, which must match the existing project configuration before substitution. Because the AFV30D family also includes 100–120 V AC and 24 V DC variants, the exact suffix must be verified against the label.

Suffix reference for AFV30D: 4 = dual-redundant Vnet/IP + dual-redundant power; 1 = fixed digit; 2 = 220–240 V AC; 5 = non-explosion-proof basic type; 2 = LFS1700 control function.
Key Selling Points & Differentiators
- Duplex controller architecture: Supports redundant CPU operation for higher availability.
- Dual-redundant Vnet/IP: Maintains network communication even if one Vnet/IP path fails.
- Dual-redundant power: Reduces single-point power failure risk inside the FCS rack.
- 220–240 V AC power: Matches common industrial AC supply systems.
- Direct CENTUM VP/CS 3000 fit: Designed for YOKOGAWA FCS racks, making it a practical OEM replacement for maintenance or spares.
- Not recommended for: 100–120 V AC or 24 V DC power systems, single-CPU replacements, explosion-proof applications, or AFV10S/AFV10D/AFV30S/AFV40D substitutions without engineering approval. Always confirm the exact suffix before ordering.
Quality Transparency SOP
Controller units should be verified beyond visual inspection.
- Incoming visual QA: Inspect factory sealing, label integrity, connector condition, PCB condition, and corrosion indicators.
- Label verification: Confirm full model , including suffix and revision, matches the required configuration.
- Power interface check: Inspect AC power terminals and grounding points for damage or oxidation.
- Communication interface check: Verify Vnet/IP Ethernet ports and status indicators.
- Final packing: Record serial/lot information, apply anti-static packaging, and seal with a condition label.
Technical Risk Avoidance
Confirm the exact suffix. The AFV30D family supports multiple power and protection options. AFV30D-A41152 is 220–240 V AC, non-explosion-proof; it is not interchangeable with 100–120 V AC or 24 V DC variants.
Match the control function code. The last digit “2” indicates the LFS1700 control function. Substitution should be confirmed against the existing CENTUM VP project configuration.
Do not substitute for AFV10S, AFV10D, AFV30S, or AFV40D without review. Different FCU families may have different compatibility, slot requirements, and software support.
Verify system version compatibility. AFV30D controllers are used across CENTUM VP releases, including upgrades to newer R6/R7 platforms, but firmware and project compatibility must be confirmed before installation.
Check redundancy configuration. Confirm whether the existing FCS uses duplex CPU, duplex power, and dual Vnet/IP before replacing the unit.
Buyer’s FAQ
Is this unit genuine YOKOGAWA?
Yes. The is an OEM YOKOGAWA CENTUM VP/CS 3000 duplex field control unit. We supply it as new original/new surplus unless otherwise stated.
t does mean?
It indicates a duplex FCU with dual-redundant Vnet/IP, dual-redundant power, 220–240 V AC, non-explosion-proof construction, and LFS1700 control function.
Can I replace an AFV30D-S41161 with this unit?
Not automatically. The power voltage, explosion protection, and control function codes must match. Substitution requires engineering confirmation.
Does it include I/O modules?
No. The AFV30D is the field control unit. I/O modules such as AAI, AAR, ADV, and ADR are separate components installed in the same FCS rack.
What is the warranty and lead time?
Each unit carries a standard 12-month functional warranty from shipment, excluding damage from incorrect installation, power mismatch, or project configuration errors. In-stock units typically ship within 1–3 business days after payment confirmation.
