- Seamless integration with CENTUM VP / CS 3000 without additional configuration
- Factory-tested to YOKOGAWA quality standards with full diagnostic LED indication
- Long service life with available spare-parts support through authorized channels
Typical Applications
- Oil & gas upstream / downstream process control
- Petrochemical plant DCS power distribution
- Power generation and utilities automation
- Pharmaceutical batch control systems
- Pulp & paper continuous process lines
- Water treatment and municipal infrastructure
System Compatibility
- YOKOGAWA CENTUM VP (all sub-versions)
- YOKOGAWA CS 3000 (R3.x and later)
- FCS Nest Types: AFV10D, AFV20D, AFV30D (verify slot assignment per engineering drawing)
- Not compatible with CENTUM XL or CENTUM μXL legacy platforms without hardware adaptation
Selection Guide
Use the decision criteria below to confirm the correct power supply module for your application:
- Platform: Confirm your DCS is CENTUM VP or CS 3000 — NFPW442-10 S2 is not interchangeable with CENTUM XL modules.
- Redundancy requirement: If 1+1 power redundancy is required, NFPW442-10 S2 is the correct choice over NFPW441-10.
- Nest slot count: Verify available power slots in the FCS nest; each redundant pair occupies two slots.
- Hardware revision: S2 revision is recommended for CENTUM VP R5.x and later; S1 may require firmware alignment.
- Load calculation: Sum all module current draws in the nest and confirm the NFPW442-10 S2 rated output is sufficient.

Replacement & Compatibility FAQ
Q: Can NFPW442-10 S1 replace S2 directly?
A: In most CENTUM VP applications yes, but verify the hardware revision note in your FCS engineering documentation before substitution.
Q: Is NFPW442-10 S2 compatible with CENTUM XL?
A: No. CENTUM XL uses a different power bus architecture. Do not interchange these modules.
Q: Do you supply tested used / refurbished units?
A: Yes. All refurbished units are fully tested and include a 90-day functional warranty. New surplus units carry the original YOKOGAWA warranty where applicable.
Q: Can I order a single unit?
A: Yes, minimum order quantity is 1 unit. Volume discounts apply for orders of 5+ units.
Q: How do I verify the module is genuine?
A: Each unit ships with its original YOKOGAWA label intact. We provide a CoC and, where available, original packaging. Contact us if you require additional authentication documentation.
