Compatible Replacement & Equivalent Models

When the original SPW481-53 S1 is unavailable or end-of-life, the following models may serve as functional equivalents or drop-in replacements depending on your system revision and nest configuration. Always confirm compatibility with your system integrator or YOKOGAWA service engineer before substitution.

YOKOGAWA SPW481-53 – Base variant without S1 suffix; verify suffix differences with YOKOGAWA BOM
YOKOGAWA SPW481-51 – Earlier revision; check output rating and connector compatibility
YOKOGAWA SPW481-52 – Intermediate revision; confirm firmware and hardware revision compatibility
YOKOGAWA PW481 – Predecessor power supply series for CS 3000 platforms
Third-party 24 V DCS power supplies – Must match output voltage, current rating, form factor, and backplane interface; not recommended without engineering validation

System Compatibility

The SPW481-53 S1 is designed for use within the following YOKOGAWA platforms:

CENTUM VP (all revisions) – Primary target platform
CENTUM CS 3000 – Compatible with appropriate FCS nest configurations
Field Control Station (FCS) – AFV10D, AFV30D, and related FCS types
Nest / Baseplate – Confirm nest model and slot assignment with YOKOGAWA system documentation

Not compatible with YOKOGAWA STARDOM, ProSafe-RS, or non-CENTUM platforms without engineering review.

Selection Guide

Use the following criteria to select the correct power supply module for your system:

Step 1 – Identify your platform: Confirm whether your system is CENTUM VP or CS 3000 and the specific FCS model number.
Step 2 – Check nest slot requirements: Verify the power supply slot position and quantity (single vs. redundant pair).
Step 3 – Confirm input voltage: Ensure your facility power (100–240 V AC) matches the module’s universal input range.
Step 4 – Verify suffix/revision: The S1 suffix may indicate a specific hardware revision or regional certification. Cross-reference with your YOKOGAWA BOM or engineering drawing.
Step 5 – Redundancy requirement: If your SIL or availability requirements mandate redundant power, order two units and confirm the redundancy wiring scheme.
Step 6 – Contact Konmask: Provide your FCS model, nest part number, and current power supply part number for a verified compatibility confirmation before purchase.

Replacement & Compatibility FAQ

Q: Can I replace SPW481-53 S1 with SPW481-53 (without S1 suffix)?
A: Possibly. The S1 suffix typically denotes a hardware revision or certification variant. Contact YOKOGAWA or Konmask to confirm interchangeability for your specific system revision.

Q: Is this module compatible with CENTUM CS 1000?
A: The SPW481 series is primarily designed for CS 3000 and CENTUM VP. CS 1000 uses a different power architecture — consult YOKOGAWA documentation before substitution.

Q: Can I use a generic 24 V DC power supply as a replacement?
A: Not recommended. The SPW481-53 S1 integrates with the FCS backplane for diagnostics and redundancy switching. A generic PSU will not support these functions and may void system warranties.

Q: What is the typical lead time for a genuine unit?
A: In-stock units ship within 1–3 business days. For sourced or new OEM units, lead time is typically 5–15 business days depending on availability.

Q: Do you provide a warranty on surplus units?
A: Yes. Konmask.com provides a 90-day functional warranty on all tested surplus units. Extended warranty options are available — contact us for details.

Q: Can Konmask assist with system-level compatibility verification?
A: Yes. Provide your FCS model, nest part number, and current BOM, and our technical team will confirm compatibility before you commit to purchase.
