Compatible Replacement & Equivalent Models
The following models are commonly evaluated as replacements or equivalents for the PW302-S4. Always verify electrical and mechanical compatibility before substitution:
- YOKOGAWA PW301-S4 — Earlier generation power supply; verify output rating compatibility
- YOKOGAWA PW302-S3 — Predecessor variant; check nest/slot compatibility
- YOKOGAWA PW481-S4 — 48 V DC output variant; not a direct drop-in replacement
- YOKOGAWA PW302-S4-R — Redundant-pair version; functionally equivalent in single-unit use
- Third-party DCS PSU modules — Must match 24 V DC output, connector pinout, and FCS nest form factor; consult Konmask engineering support for validation
Note: Konmask.com recommends using genuine YOKOGAWA OEM parts for safety-critical DCS applications. Third-party alternatives should be validated by a qualified automation engineer.

Selection Guide
Use the following criteria to confirm the PW302-S4 is the correct module for your application:
- Step 1 — Confirm DCS platform: CENTUM VP or CS 3000 required
- Step 2 — Verify output voltage: System must require 24 V DC regulated supply
- Step 3 — Check nest slot: Confirm PSU slot designation in your FCS nest layout drawing
- Step 4 — Redundancy requirement: If 1+1 redundancy is needed, order two (2) units
- Step 5 — Input voltage: Confirm site AC supply is 100–240 V AC, 50/60 Hz
- Step 6 — Certifications: Verify CE/UL requirements for your region and industry

Replacement & Compatibility FAQ
Q: Can the PW302-S4 replace a PW301-S4 directly?
A: In most CENTUM VP systems, yes — but verify the nest slot assignment and output current rating match your load requirements before substitution.
Q: Is the PW302-S4 compatible with CS 3000?
A: Yes. The PW302-S4 is designed for both CENTUM VP and CS 3000 FCS nests. Confirm your nest model with YOKOGAWA documentation.
Q: Can I use two PW302-S4 units for redundancy?
A: Yes. The PW302-S4 supports 1+1 redundant configuration when two units are installed in the designated PSU slots of the FCS nest.
Q: Do you supply new or refurbished units?
A: Konmask.com supplies both new OEM stock and professionally tested surplus units. Condition is clearly stated on each listing. Contact us if you require new-only supply.
Q: Can you provide a certificate of conformance (CoC)?
A: Yes. CoC and inspection reports are available upon request for regulated industries.
