Note: Public listings identify PW482-10 S2 as a Yokogawa CENTUM VP power supply module, with “S2” used as a style or revision code. Exact output ratings, mechanical dimensions, and compatible FCS models should be confirmed from the module nameplate or Yokogawa hardware manual.
Product Introduction
The PW482-10 S2 is a Yokogawa CENTUM VP Field Control Station power supply module designed for 220–240 V AC input applications. In CENTUM VP systems, power supply modules provide regulated internal DC power to processors, I/O nodes, and communication components within the FCS rack.
The “S2” code is commonly referenced as a style or revision identifier for the PW482-10, indicating a specific manufacturing revision or configuration variant. Because CENTUM VP power supplies must match the FCS model, input voltage, and redundancy configuration, the PW482-10 S2 is mainly used for replacement, maintenance, and spare-parts provisioning in existing Yokogawa DCS installations.
For system integrators and maintenance teams, verifying the style code is important. A PW482-10 with a different revision or style may not be a direct drop-in replacement without confirming compatibility with the existing FCS rack and project configuration.
QA & Inspection SOP
Each unit is inspected before release:
- Nameplate verification: Confirm the model reads PW482-10 and the style code reads S2.
- Visual inspection: Check the housing, terminals, connectors, and mounting hardware for damage.
- Terminal check: Inspect AC input terminals and system-side connectors for corrosion, looseness, or burn marks.
- Insulation check: Verify no visible short circuits between input, output, and ground.
- Power-on test: Apply rated 220–240 V AC input and confirm normal output voltage.
- Status check: Verify module status LEDs or alarm indicators after startup.
- Redundancy check: If used in a redundant pair, confirm both power supplies match model, style code, and output characteristics.
- Packaging: Protect terminals and connectors with anti-static packaging.
Full system validation requires installation in a compatible CENTUM VP FCS rack with authorized configuration access.
Installation Pitfalls & Guide
❗ Confirm input voltage. PW482 is specified for 220–240 V AC input. Do not substitute with PW481 (100–120 V AC) or PW484 (24 V DC) without verifying voltage and FCS compatibility.
❗ Match the style code. The S2 suffix is a style or revision code. Replacing a PW482-10 S2 with a non-S2 unit may affect compatibility, even if the base model is the same.
❗ Verify FCS compatibility. PW482 modules are designed for CENTUM VP Field Control Stations, not generic 24 V DC supplies or unrelated Yokogawa platforms.
❗ Check redundancy configuration. If the original power supply was installed as a redundant pair, both units should match in model, style code, and revision.
❗ Follow plant electrical safety procedures. AC power supply replacement should follow lockout/tagout and site maintenance procedures.
Installation steps:
- Pre-install: Record the original module model, style code, slot position, and wiring.
- Isolate power: De-energize the FCS power input according to site safety procedures.
- Install: Seat the PW482-10 S2 firmly in the correct FCS power slot.
- Wire: Reconnect AC input and system connectors according to the original wiring.
- Power-up: Restore AC power and check module status indicators.
- Verify: Confirm normal FCS operation and absence of power alarms.
Technical FAQ
is S2?
It is a Yokogawa CENTUM VP Field Control Station power supply module for 220–240 V AC input, with S2 as the style or revision code.
Which system does it belong to?
It belongs to the Yokogawa CENTUM VP FCS power supply family.
Can it replace a PW482-10 without S2?
Not without verification. The S2 code may indicate a specific revision or configuration. Confirm compatibility with the existing FCS rack and hardware manual before substitution.
What should I check before ordering?
Confirm the full model code, style code (S2), original FCS model, input voltage, redundancy requirement, and revision. A nameplate photo is the most reliable way to verify compatibility.
If you can share the module nameplate or the CENTUM VP FCS model, I can confirm whether the S2 revision is a direct match for your rack configuration.
