Reflow Oven Control Solution – BTU International 5225S Quad I/O Board | 5225 Series
Where This Product Is Used
The BTU International 5225S Quad I/O Board (P/N 4080395-004, Assembly No. 91-5225SU-28R, Board Rev. 0200-02866) is the primary multi-channel I/O interface PCB installed inside BTU Pyramax and Paragon series convection reflow soldering ovens. It is found in high-volume SMT (Surface Mount Technology) production lines across:
- Electronics contract manufacturing (EMS/CM) facilities
- Automotive ECU and power module assembly lines
- Aerospace and defense PCB soldering operations
- Medical device board assembly cleanrooms
- LED and semiconductor packaging lines
When this board fails, the entire reflow oven goes offline — making fast, accurate sourcing of this exact part number critical to minimizing production downtime.

Application-Specific FAQ
Q: Is this board compatible with the BTU Pyramax 98N?
A: The 5225S Quad I/O Board is designed for the 5225S platform. Pyramax compatibility depends on the backplane revision — contact us with your oven serial number for confirmation.
Q: Can this board be repaired instead of replaced?
A: Component-level repair is possible for some failure modes (blown fuses, failed optocouplers). However, for production-critical lines, direct replacement with a tested board minimizes risk and downtime.
Q: Does the kit 93-5200 include all connectors needed for installation?
A: Yes — Kit 93-5200 contains the mating connector hardware required for the 91-5225SU-28R board installation per BTU service documentation.
Q: What is the typical failure symptom for this board?
A: Common symptoms include zone temperature read errors, conveyor speed faults, or oven safety interlock alarms that persist after sensor replacement — all pointing to I/O board failure.
