Selection Guide
Use the following criteria to confirm the NFPW441-10 is the correct module for your application:
- Platform check — Confirm your FCS node is CENTUM VP or CS 3000 series.
- Input power — Verify site AC supply is 100–240 V AC, 50/60 Hz.
- Load calculation — Total I/O module current draw must not exceed 10 A / 240 W per power module.
- Redundancy requirement — For critical loops, deploy two NFPW441-10 units in parallel redundant mode.
- Slot position — Install in the designated power slot of the CENTUM VP node unit (refer to IM 33J01B10-01EN).
- Suffix selection — Choose /CE for EU CE marking compliance; /KS for Korean market certification.

Replacement & Compatibility FAQ
Q: Can NFPW441-11 directly replace NFPW441-10?
A: In most cases yes — the -11 suffix indicates a minor revision. Verify with YOKOGAWA’s revision history document (IM 33J01B10-01EN) for your specific FCS firmware version.
Q: Can I use a third-party 24 V DC power supply instead?
A: Technically possible if voltage/current specs match, but this voids YOKOGAWA system certification and may affect SIL ratings. Not recommended for safety-critical loops.
Q: Is the NFPW441-10 compatible with CENTUM VP R6.x?
A: Yes. The NFPW441-10 is compatible with CENTUM VP through R6.x. Confirm with your YOKOGAWA system integrator for the latest hardware compatibility matrix.
Q: What is the lead time for NFPW441-10?
A: In-stock units ship within 1–3 business days. For out-of-stock scenarios, typical lead time is 4–8 weeks from YOKOGAWA factory. Contact us for current availability.
Q: Do you provide a test report with the module?
A: Yes. A functional test report is available upon request for all units shipped from Konmask.
