- The Limelight DFI-100 platform discriminates between ignitor Flame and No Flame conditions
- The self-contained electronics mount in an ignitor control cabinet or nearby junction box
- The DFI-100 platform supports flame-rod and optical-detector sensing arrangements
DFI-100-340F is an ALSTOM Limelight diagnostic flame indicator for ignitor flame proving.
Manufacturer DFI-100 documentation describes a self-contained unit that analyzes a flame-rod or optical signal, indicates flame quality and faults, and provides relay and process interfaces to the surrounding burner system.
Because the accessible manufacturer manual describes the DFI-100 family rather than the complete -340F suffix, verify the physical nameplate, supply, terminal diagram, sensing method, configuration, and replacement revision before service.
Availability, condition, price, and shipping time for DFI-100-340F are confirmed during quotation.
