Product Description
The SPW484-53-S1 is an industrial-grade DC-to-DC power conversion module for Yokogawa CENTUM VP and FIO hardware platforms. Designed for 24 V DC input systems, it provides a stable and reliable power foundation for Field Control Units (FCUs) and I/O nodes. The “53” designation identifies this as a hardened module with ISA Standard G3 conformal coating and an extended operating temperature range. The “S1” revision represents a hardware update focused on enhanced component durability and thermal performance in corrosive or thermally volatile industrial environments.

Advanced Protection & Resilience
-
Harsh environment readiness: ISA G3 coating protects against corrosive gases (H₂S, Cl₂), common in wastewater and petrochemical facilities.
-
Extended temperature range: Reliable operation in non-climate-controlled field enclosures from -20°C to +70°C.
-
Redundant fail-safe design: Dual modules share the load; if one fails, the other immediately takes over without interrupting system operation.
-
S1 hardware revision: Improves thermal efficiency and reduces EMI, enhancing long-term module reliability.
Technical FAQ
Q: Is the SPW484-53-S1 compatible with standard PW484 modules?
A: Electrically yes, but for redundancy or harsh-environment deployments, two identical G3-coated SPW484-53-S1 modules are recommended to ensure consistent performance.
Q: What improvements does the S1 revision provide?
A: The S1 suffix indicates refined internal power-stage components, typically offering lower EMI and improved thermal performance compared to the base SPW484-53 model.
