Selection Guide
Use the following decision criteria to confirm the SPW484-13 is the correct module for your application:
- Step 1 — Confirm DCS platform: Verify your system is CENTUM VP or CS 3000. Other YOKOGAWA platforms (STARDOM, ProSafe-RS) use different power modules.
- Step 2 — Check input voltage: Confirm site power is 100–240 V AC. For 24 V DC input sites, a different SPW variant is required.
- Step 3 — Assess redundancy requirement: If your FCS requires redundant power, order two units and configure per YOKOGAWA wiring guidelines.
- Step 4 — Verify nest slot: Confirm the power supply slot in your nest is designated for the SPW484 series.
- Step 5 — Check revision: SPW484-13 is the current revision. If your system documentation specifies an earlier revision, contact Konmask to confirm interchangeability.

Replacement & Compatibility FAQ
Q: Can the SPW484-13 replace an SPW484-11 or SPW484-12?
A: In most cases yes — the -13 is the latest revision and is backward-compatible with earlier -11 and -12 revisions. Confirm with YOKOGAWA release notes for your specific FCS firmware version.
Q: Is the SPW484-13 compatible with CENTUM CS 1000?
A: No. CS 1000 uses a different power module family. Contact Konmask for the correct CS 1000 power supply.
Q: Can I use a third-party power supply as a replacement?
A: Not recommended for safety-critical DCS applications. Non-OEM modules may void YOKOGAWA support agreements and introduce reliability risks.
Q: What is the lead time for the SPW484-13?
A: Typically 3–15 business days depending on stock. Contact us for real-time availability.
Q: Do you provide a warranty?
A: Yes. Konmask provides a 90-day functional warranty on all modules. OEM warranty terms apply where applicable.
