Replacement & Compatibility FAQ
Q: Can the SDV531-S33 replace a Fisher DVC6200 directly?
A: Functionally yes for HART 4–20 mA loops, but mounting brackets differ. A NAMUR adapter kit is required for direct actuator mounting. Contact us for adapter availability.
Q: What does the “-S33” suffix mean?
A: The S33 suffix indicates dual explosion-proof certification: intrinsically safe (Ex ia) and flameproof (Ex d), suitable for Zone 1 and Zone 2 hazardous areas.
Q: Is the SDV531-S33 compatible with FOUNDATION Fieldbus?
A: No. The SDV531 series uses HART. For FF, select the SDV532-S33.
Q: Can I configure the SDV531-S33 without YOKOGAWA FieldMate?
A: Yes. Any HART-compatible handheld communicator (e.g., Emerson 475/375) or AMS Device Manager with the YOKOGAWA DD file can be used.
Q: What is the minimum supply pressure?
A: 140 kPa (1.4 bar / 20 PSI). Ensure your instrument air supply meets this minimum for reliable operation.
