Compatible Replacement & Equivalent Models
When the PW482-51 is discontinued, difficult to source, or requires a cost-effective alternative, the following models may serve as functional equivalents. Always verify electrical and mechanical compatibility before substitution.
- Yokogawa PW481-51 — Earlier generation PSU; verify output rating and connector pinout
- Yokogawa PW484-51 — Higher-capacity variant; check FCS slot compatibility
- Yokogawa PW482-50 — Alternate suffix; confirm firmware and hardware revision
- Third-party 24 V DC DIN-rail PSU — Must meet CENTUM VP input spec; not recommended for safety-critical loops without validation
Note: Konmask.com recommends using original Yokogawa modules for safety-instrumented systems. Contact our team for cross-reference validation.

Selection Guide
Use the following criteria to confirm the PW482-51 is the correct module for your application:
- Step 1 — Confirm DCS platform: Verify your system is CENTUM VP or CS 3000
- Step 2 — Check FCS model: Match the FCS type to supported PSU slots
- Step 3 — Verify input voltage: Confirm site AC supply is 100–240 V
- Step 4 — Redundancy requirement: If N+1 redundancy is required, order two units
- Step 5 — Revision check: Confirm hardware suffix (-51) matches your cabinet revision
- Step 6 — Contact Konmask: Send your FCS model number for free cross-reference confirmation

Replacement & Compatibility FAQ
Q: Can PW482-51 replace PW481-51 directly?
A: In most CENTUM VP installations, yes — but verify the output connector and firmware revision before hot-swapping.
Q: Is the PW482-51 still in production?
A: Yokogawa periodically revises its PSU lineup. Contact Konmask for current availability and lead time.
Q: Can I use a generic 24 V PSU as a replacement?
A: Not recommended for certified DCS installations. The PW482-51 includes DCS-specific protection circuits not present in generic units.
Q: Do you supply refurbished units?
A: Yes. Refurbished units are available with full testing reports. New and refurbished pricing available on request.
Q: What is the lead time?
A: Typically 3–7 business days for in-stock units; 2–4 weeks for sourced orders.
