Product Introduction

The PW482-10 S2 is a power supply module used in the YOKOGAWA CENTUM CS 3000 Field Control Station. It supplies regulated power to the FCU rack and supports dual-redundant operation so a single module failure does not trip the control station.

For plants maintaining CS 3000 installations, this is a critical spare. Redundant power supplies are often the difference between a minor alarm and an unplanned station shutdown. This unit is supplied as new original or new surplus, depending on stock availability.

 

QA & Testing SOP

Each unit is inspected before dispatch:

• Visual & connector inspection: Check front panel, housing, backplane connector pins, labeling, and signs of heat stress, corrosion, or pin damage.
• Authenticity verification: Confirm YOKOGAWA branding, model marking, suffix code S2, serial/lot information, and connector quality to screen non-OEM parts.
• FCU rack power-on test: Install the module into a compatible CENTUM CS 3000 FCU test rack and verify power-up behavior and LED indicators.
• Output voltage check: Measure regulated DC output under no-load and resistive load using a calibrated DC load and Fluke multimeter.
• Redundancy handover test: Where test conditions allow, verify dual power supply operation and failover behavior without disturbing adjacent modules.
• Anti-static packaging: Packed in ESD-safe shielding bags with protective foam to prevent transit damage.

 

Installation Pitfalls & Guide

❗ Match the suffix code exactly. For dual-redundant operation, both power supply modules must have the same suffix code. Mixing PW482-10 variants can prevent proper redundancy.

❗ Never remove both power supplies at the same time. In a redundant FCU rack, pulling both units simultaneously can shut down the entire station.

❗ Confirm which unit is active before removal. Check LED status and system diagnostics first. Remove the standby unit first whenever possible.

❗ Do not force the module into the slot. FCU backplane connectors are precision-mated. Bent pins can damage both the module and the rack.

Replacement steps:

1. Pre-install: Verify slot position, redundancy status, suffix code S2, and cabinet input power.
2. Removal: Loosen retaining screws, confirm the standby unit is healthy, and withdraw the module straight out.
3. Install: Align the guide rails, slide the module in firmly but gently, and secure the front-panel screws.
4. Power-on test: Confirm LED status, output voltage, FCU rack health, and redundancy operation.

 

Technical FAQ

Is pricing flexible for multiple units? Yes. Price depends on condition, quantity, and lead time. New original and new surplus units are quoted separately. Send your quantity and we can provide a project-level quote.

What warranty is included? Standard warranty is 12 months from shipment for functional defects. This covers pre-shipment or manufacturing failures, not damage from incorrect installation, wrong input power, or environmental misuse.

Why must both redundant modules have the same suffix code? YOKOGAWA specifies that dual-redundant configuration requires two identical modules with the same suffix code. Mismatched variants may have different internal characteristics, which can prevent proper load sharing or failover.

Can I hot-swap this power supply? Yes, the module supports hot replacement. However, only replace one unit at a time and confirm the remaining module is healthy before removal.

Is this still available given CS 3000 obsolescence? CS 3000 is a mature platform, and original factory supply is limited. We source tested new surplus and remaining OEM stock to support existing installations. If you need multiple units, confirm availability early.
