Compatible Replacement & Equivalent Models
When the PW482-S01 is unavailable or end-of-life, the following models may serve as functional replacements or equivalents. Compatibility must be verified against your specific system revision and firmware version before installation.
| Model | Manufacturer | Notes |
|---|---|---|
| PW482-S11 | YOKOGAWA | Upgraded variant; confirm backplane compatibility |
| PW481-S01 | YOKOGAWA | Lower-capacity predecessor; verify load requirements |
| PW484-S01 | YOKOGAWA | Higher-output variant for expanded I/O configurations |
| PW701-S01 | YOKOGAWA | STARDOM platform PSU; not a direct drop-in |
Important: Third-party or cross-brand replacements are not recommended for safety-critical DCS applications without full engineering validation.
Why Choose the Original Model
- Platform-native design: Engineered specifically for CENTUM VP / CS 3000 backplane architecture — no compatibility risk.
- Redundancy support: Supports N+1 redundant power configurations for high-availability systems.
- Proven field reliability: Deployed globally in refinery, chemical, and power generation facilities.
- OEM warranty & support: Eligible for YOKOGAWA service contracts and firmware updates.
- Regulatory compliance: Meets IEC 61511 / IEC 61508 functional safety requirements when used as specified.
Typical Applications
- Oil & gas refinery DCS power distribution
- Chemical plant process control stations
- Power generation and utilities automation
- Pharmaceutical batch control systems
- Pulp & paper continuous process control
- Water treatment and municipal infrastructure SCADA/DCS
System Compatibility
The PW482-S01 is designed for integration within the following YOKOGAWA system families:
- CENTUM VP (all revisions — confirm with YOKOGAWA engineering for R6.x and above)
- CENTUM CS 3000 (R3.x series field control stations)
- AFV10 / AFV20 / AFV30 field control units (verify slot assignment)
Not compatible with YOKOGAWA STARDOM, ProSafe-RS, or FAST/TOOLS platforms without additional engineering review.
Selection Guide
Use the following criteria to confirm the PW482-S01 is the correct module for your application:
- Step 1 — Platform check: Confirm your DCS is CENTUM VP or CS 3000. Check the FCS model number on the cabinet label.
- Step 2 — Load calculation: Sum the power draw of all I/O modules in the station. Ensure PW482-S01 output capacity covers total load with ≥20% headroom.
- Step 3 — Redundancy requirement: If your SIL or availability spec requires redundant power, order two units and confirm the redundancy module (if required) is included.
- Step 4 — Revision matching: Match the hardware revision suffix (-S01) to your existing installed base to avoid firmware or connector incompatibilities.
- Step 5 — Spare ratio: For critical processes, maintain a minimum 1:5 spare ratio (one spare per five installed units).

Replacement & Compatibility FAQ
Q: Can I use PW482-S01 in a CENTUM VP R6.09 system?
A: Generally yes, but confirm with YOKOGAWA’s compatibility matrix for your specific FCS hardware revision. Contact us and we can assist with verification.
Q: Is PW482-S01 interchangeable with PW482-S11?
A: The S11 is an updated variant. Physical form factor is similar, but firmware and backplane signaling differences may exist. Engineering validation is required before substitution.
Q: Do you supply new or refurbished units?
A: We supply both new (factory-sealed) and tested-refurbished units. Condition is clearly stated on each listing. Contact us to specify your requirement.
Q: Can I get a datasheet or wiring diagram?
A: Yes. Contact support@konmask.com with your part number and we will provide available technical documentation.
Q: What is the lead time?
A: In-stock units ship within 1–3 business days. Out-of-stock items are sourced on request — typical lead time 2–6 weeks depending on availability.
