Application-Specific FAQ
Q: Is the PW482-10 S2 compatible with both CENTUM VP and CS 3000?
A: Yes. The PW482-10 S2 is designed for use across YOKOGAWA’s CENTUM platform family. Always verify cabinet slot compatibility with your system revision documentation.
Q: Can two PW482-10 S2 modules operate in parallel for redundancy?
A: Yes. YOKOGAWA’s CENTUM power architecture supports N+1 redundant power supply configurations. Both modules share the load and one takes over automatically upon failure of the other.
Q: What is the difference between PW482-10 and PW482-10 S2?
A: The S2 suffix denotes a second-generation revision with enhanced EMC filtering and improved thermal management. It is backward-compatible with original PW482-10 slots.
Q: Do you supply the module with a warranty?
A: Yes. Refurbished and surplus units carry a 12-month functional warranty. New factory-sealed units carry the original YOKOGAWA manufacturer warranty.
Q: Can this module be used outside of a YOKOGAWA DCS system?
A: The PW482-10 S2 is optimized for CENTUM backplane integration. Use in non-YOKOGAWA systems is not recommended and may void warranty.
Q: What documentation can you provide?
A: We can supply the YOKOGAWA datasheet, test report, and packing list. For regulated industries, serial number traceability records are available on request.
