Flame relay failure in multi-burner setups causes unplanned shutdowns, inconsistent combustion, and costly downtime — especially in continuous-operation boiler plants where one faulty flame safeguard module can take an entire line offline.The Azur FRS100C100 is a Japanese-imported flame relay controller designed for multi-burner control applications. It monitors flame presence across multiple burners and signals the main controller to maintain or cut fuel supply. The unit shown in the disassembled view exposes the internal relay contacts, detection circuitry, and terminal layout — useful for maintenance teams verifying component condition or sourcing compatible replacement parts.Core Parameters

Core Advantages
- Multi-burner sequencing support — handles flame monitoring across several burners from one controller, reducing wiring complexity in large boiler or furnace installations.
- Japanese-grade relay contacts — silver-alloy contacts rated for high-cycle switching in environments with vibration and thermal cycling typical of power plant and refinery burners.
- Disassembled-ready diagnostics — the modular internal layout shown in the product image lets field technicians inspect contact wear, coil integrity, and terminal corrosion without sending the unit back to the lab.
- Drop-in compatibility with Azur FRS100 series — fits existing FRS100 control panels and cable harnesses, minimizing retrofit downtime when replacing aged flame relays in petrochemical or food-processing boiler lines.
Applicable Industries & ScenariosIndustrial steam boilers, waste-heat recovery furnaces, food-drying burner systems, refinery process heaters, ceramic kiln multi-burner rigs, and any continuous-combustion setup using Japanese burner management systems.
