Yokogawa CENTUM VP spares and module repair in India
CENTUM VP is Yokogawa’s distributed control system (DCS). Star Automations sources CENTUM VP and CS 3000 I/O modules, processor modules, power supplies and bus couplers, and repairs these modules at board level where circuits and parts allow. Send the full module code from the label, for example AAI143 or ADV551 with its suffix, and we confirm availability or repairability.
Star Automations is an independent multi-brand repair and supply company and is not an OEM service centre.
How CENTUM VP fits together, and how an enquiry works
Modules we repair at board level where circuits and parts allow: processor, power supply, bus and I/O modules.
Names follow Yokogawa’s published CENTUM VP specifications. Your system may use a different mix.
- STEP 1Send the model codeA nameplate or label photo on WhatsApp is enough.
- STEP 2We checkAvailability and repairability, before you ship anything.
- STEP 3Supply, repair or alternativeThe route that is practical for your part.
- STEP 4Test and returnEach repaired unit is bench-tested first.
Controller, power and bus modules we handle
The model names below come from Yokogawa’s published CENTUM VP general specifications. Your plant may use a different mix, so send the label photo of the module you need.
| Module family | Model examples | Function |
|---|---|---|
| Field control unit (FCU) | AFV30S, AFV30D, AFV40S, AFV40D | Controller unit for FIO; the D versions are duplexed (dual-redundant) |
| Processor modules | CP461, CP471 | Processor cards in the FCU; two identical cards form a redundant pair |
| Power supply modules | PW481, PW482, PW484 | Power supplies in the FCU and node units |
| ESB bus couplers | EC401, EC402 | Connect node units to the FCU over the ESB bus |
| Optical ESB bus repeaters | ANT401, ANT411, ANT502, ANT512 | Extend the ESB bus over optical fibre |
| Node units | ANB10S, ANB10D, ANB11S, ANB11D | Rack-mounted node units for single or dual-redundant ESB bus |
I/O modules most often asked for
I/O modules carry field signals and take the brunt of surges, so they are usually the first parts a plant needs.
| Module | Function |
|---|---|
| AAI141, AAI143 | Analog input, 4-20 mA, 16 channels (AAI143 isolated) |
| AAI543 | Analog output, 4-20 mA, 16 channels, isolated |
| AAI841, AAI835 | Analog input and output, 4-20 mA, combined channels |
| AAV141, AAV144, AAV544 | Voltage input and output (1-5 V, or −10 to 10 V on the isolated types) |
| AAT145 | Thermocouple and mV input, 16 channels, isolated |
| AAR145 | RTD and potentiometer input, 16 channels, isolated |
| ADV151, ADV161 | Digital input, 24 V DC, 32 and 64 channels, isolated |
| ADV551, ADV561 | Digital output, 24 V DC, 32 and 64 channels, isolated |
Board-level repair of CENTUM modules
What we repair
CENTUM VP and CS 3000 I/O modules, processor modules, power supply modules and bus couplers, at board level where circuits and parts allow.
How it works
Send the module label and the symptom first. We confirm repairability from your photo, repair the board, and bench-test the module before return.
When we advise otherwise
If a module cannot be repaired economically or a part is no longer obtainable, we say so and offer tested surplus stock, spares consignment or a migration route.
What to send for a module quote
The base module name is not enough. Suffix and style codes decide which version fits your system, and a module from a different style may not be a drop-in match.
- Full module code from the label, for example ADV551 with its suffix
- Style code and serial number if printed on the label
- The system: CENTUM VP, CS 3000 or CS 1000, and the FCU type if known
- Symptom in one line, and the LED status if you can see it
- Quantity, and whether you need repair or a replacement module
Follow your site procedure and Yokogawa’s documentation when replacing any module in a running system.
Older CENTUM systems and critical spares
CS 3000, CS 1000 and CENTUM XL hardware is ageing in many plants. Three practical routes: keep a tested critical-spares set through spares consignment, repair failed modules and keep them as spares, or plan a staged upgrade with a migration audit. See repair or replace advice for how to decide.
Send the model code
Name, contact and the nameplate photo are enough to start.

Common questions
What is CENTUM VP?
CENTUM VP is Yokogawa’s distributed control system for process plants. It combines field control units, I/O modules, bus modules and operator stations. It is the successor to the CENTUM CS 3000 generation.
Do you repair CENTUM VP and CS 3000 modules?
Yes. We repair CENTUM I/O modules, processor modules and power supply modules at board level where circuits and parts allow. We confirm repairability from the label photo and symptom before you ship, and bench-test the module before return.
Which CENTUM modules are needed most often?
In plants the I/O modules fail most often, such as analog input AAI143, digital input ADV151 and digital output ADV551, followed by power supply modules. Surges on field wiring, heat and age decide which one fails in your plant.
Can you supply CENTUM modules in India?
Yes. We source CENTUM modules as new surplus, refurbished-and-tested or used stock, and the condition is stated in the quote. Send the full module code with suffix and style and we confirm availability.
Do you handle discontinued CENTUM CS 3000 and older parts?
Yes. For discontinued items we source from surplus stock first, then offer repair, spares consignment or a migration route. Ask for a critical-spares list before the next shutdown.
What should I send for a module quote?
The full module code from the label with suffix and style, the system type, the symptom, the quantity and the delivery location. A clear photo of the label is the fastest way to start.
Are you a Yokogawa authorised dealer or service centre?
No. Star Automations is an independent multi-brand repair and supply company and is not an OEM service centre. For new CENTUM systems, engineering and licences, contact Yokogawa or its channel partners.
Is a repaired module safe to use in a running DCS?
Test the repaired module in your own procedure before relying on it. Our bench test checks the repaired board, but only your plant can confirm behaviour in the live system. For ProSafe-RS or other safety functions, follow your functional-safety procedure.
