Industrial burner systems go down when flame detection fails. OEM flame relays are hard to source, lead times stretch weeks, and third-party replacements often misfire under high-heat cycling. The Ayambu FRS100C100 multi-burner flame relay controller solves this — genuine Japanese-made, pulled from working units, ready to drop into your existing control panel.What This IsThe FRS100C100 is a flame supervision relay designed for multi-burner industrial combustion setups. It monitors flame signals across several burners simultaneously, confirms stable ignition, and sends a lockout signal if flame loss is detected. Units offered here are disassembled original parts — fully inspected, electrically tested, and sourced from decommissioned Japanese equipment. No refurbs, no clones.Core Parameters

Why This Unit Over Generic Replacements
- True multi-burner sequencing. Unlike single-channel relays, the FRS100C100 handles staggered ignition and flame-proofing across multiple burners — critical for large furnace and boiler rigs where one missed flame can trigger a full shutdown.
- Built for sustained heat cycles. Japanese-spec components in this unit are rated for continuous operation above 60°C ambient, common in ceramic kilns, reflow ovens, and process heaters where cheap relays drift or weld contacts within months.
- Direct OEM fit. Wiring layout, terminal spacing, and relay logic match the original Ayambu control board. No rewire, no PLC reprogram — swap and run.
- Proven in harsh combustion environments. These units came out of operating industrial plants in Japan, meaning they already survived real soot, vibration, and voltage fluctuation.
Applicable Industries & Use Cases
- Industrial boilers (gas/oil fired, multi-burner configurations)
- Ceramic and glass kilns
- Metal treatment and annealing furnaces
- Food processing ovens and dryers
- HVAC rooftop units with staged combustion
- Any legacy Ayambu burner control system requiring FRS100C100 replacement
